To prevent doors from remaining open, they used to use a banal spring, but today they install a door closer. Its design is also based on a spring, but it is more powerful, hidden in a metal case and filled with oil - for “braking” when closing. Installing a door closer is not a difficult task. Self-installation will take 20-30 minutes. Hardly any more. So we take a drill and install it ourselves.

Classification

According to global standards EN 1154, door closers are classified according to the closing force they can generate. They are divided into 7 classes, which are designated EN1-EN7. When choosing a class, pay attention to the inertia of the door, that is, the width of its leaf and weight at the same time. If different door parameters correspond to different classes, install a device of a higher class.

Door closer class	Door leaf width, mm	Door leaf weight, kg
EN1	up to 750 mm	up to 20 kg
EN2	up to 850 mm	up to 40 kg
EN3	up to 950 mm	up to 60 kg
EN4	up to 1100 mm	up to 80 kg
EN5	up to 1250 mm	up to 100 kg
EN6	up to 1400 mm	up to 120 kg
EN7	up to 1600 mm	up to 160 kg

For example, the width of the door corresponds to class EN2, and the weight is EN4. They put it in 4th class, since a weaker force will not cope with the load.

There are door closers that belong to the same class. The characteristics then indicate a class with one digit - EN5. They have a small range of force adjustment - within one class. There are devices whose closing force is regulated within several groups. In this case, the range is marked with a hyphen - EN2-3, for example. The latter are more convenient to use - you can adjust the closing speed depending on the weather. But the cost of such models is higher.

Designs and traction device

The main design element of a door closer is a spring that pushes the lever. There are two types of devices based on the method of transmitting force from a spring to a lever:

Both of these types consist of two parts: a housing in which the spring is hidden and a force-transmitting mechanism and lever. They are mounted at the top of the door: one part on the leaf, the second on the frame. Which one goes where depends on the direction of opening. If the doors open “pull”, a housing with a mechanism is installed on the door leaf; when opening “pull,” a lever is attached. The photo shows a lever type closer, but similar installation rules apply to models with a sliding channel.

As you understand, they are not suitable for all types of doors; installing them on glass doors is problematic. There is another design for them - floor-mounted. The housing with the mechanism is mounted on the floor, only the holder plate protrudes from above. A similar holder is installed at the top, but the mechanism is not always there, only for heavy door leaves.

By the way, there are floor models for wooden and metal doors. They also have a linkage or sliding channel transmission. They are less conspicuous, but with this arrangement they are more likely to be damaged.

Where to put

Basically, closers are installed on external or entrance doors; they can be installed on gates or gates. In the case of doors, they are positioned so that the body is in the room. Although there are frost-resistant models designed for cold use, it is better that the case is protected from the effects of weather conditions. This arrangement also guarantees greater safety.

Installing a door closer: instructions with photos

To install the closer on the door, you only need a drill, a ruler, a pencil and a screwdriver. A drill is usually required “3” (three), but you need to look at the diameter of the fastener, which usually comes with the kit.

Most manufacturers, to facilitate self-installation door closer, completes the product with installation templates. These templates schematically depict the parts of the closer in full size. They also have mounting holes for each element. In models that can create opening forces of different classes, the holes are drawn different colors, in addition they are signed - the door closer class is placed next to it.

The template is printed on both sides of the sheet. On one side - for opening the doors "towards you" - from the side of the hinges (pictured above), on the other - "from you".

The template has two perpendicular red stripes. We align the horizontal one with the top edge of the door leaf, the vertical one with the axis line of the hinges.

Everything is clear with the upper edge of the door leaf, but to avoid mistakes during installation, you need to draw the axis line of the hinges. If the door closer is installed from the hinge side, there are no problems - use a long ruler and pencil to move the line of the middle of the hinges upward. If installation will be carried out on the other side, measure the distance from the edge of the canvas to the middle of the loop. Mark this distance on the other side and draw a line.

Holes for door closer

On the template we find marks for holes according to the selected class. Using a drill or awl, we transfer them to the door leaf and frame.

Typically, the kit includes two types of fasteners: for metal (metal-plastic) and wood. Choosing a drill suitable size and use a drill to drill holes in the marked places.

Door closers are equipped with two types of fasteners - for metal and wooden doors

Next, the actual installation of the door closer begins. Please note that for installation it is necessary that the housing and arms are disconnected. If they are assembled, they are separated (the washer is unscrewed, the screw connecting the levers and the body is removed).

Installation

We attach the parts to the holes made and install the fasteners. In the diagram we find the class of opening force that we need (in in this case EN2) and install the parts as shown in the figure.

To open “towards you,” we place the body on the door leaf and install a rod on the frame.

Now you need to connect the traction lever to the body. There is a special protrusion at the bottom of the case. We put a lever on it and tighten it with a screw.

Now all that remains is to connect the lever to the rod. There are two options.

Connect the lever to the rod

The connection of the lever with the rod itself is very simple: the two parts are combined and slightly pressed with your fingers. They lock into place with a slight click. The trick is how to position them relative to the door. The rate of movement of the door leaf at the final stage of closing depends on this. The position can change due to the fact that the rod consists of two parts and can be adjusted in length - one of the parts of the rod is a long threaded pin. Rotate the pin to shorten or lengthen it.

If you just need a smooth finishing, the rod is placed so that it is perpendicular to the door leaf. To do this, reduce its size slightly (pictured on the left).

If the door has a latch, a significant force is required to overcome its resistance. For this option, a shoulder is placed perpendicular to the door (the rod is untwisted, making it longer).

Having arranged the parts accordingly, they are combined and connected. That's all, the installation of the door closer is complete. And you can handle it with your own hands, and without special labor. The final stage remains - setting the closing speed. To do this, you need to understand the adjustments of door closers.

How to put on a gate

Frost-resistant models that can be used outside are suitable for installation on a gate. But not all gates have a top crossbar. But everyone has side racks. In this case, the rod is attached to the side post by unfolding the mounting plate along the post.

But hydraulic devices (discussed in this article) do not do well in the cold. The oil that is poured into the body and serves to “brake” the door leaf becomes more viscous, and the gate closes more slowly. From this point of view, it is better to choose a pneumatic model for the gate (about selection and installation).

How to install on a metal door

Installation of a closer on metal doors differs only in the type of fasteners used and the size of the drill. Since the canvas is usually heavier, powerful models of at least class 5 are selected (check the table). Accordingly, on the installation template you will need markings for another class.

You may also need a more powerful drill, but these are all details. Otherwise, you need to install a closer on metal doors in the same way as wooden or metal-plastic ones.

Adjusting the door closer

Closers that are installed on doors have different designs and the adjusting screws are located in different places. Everything is exactly indicated in the passport or installation instructions. But, in general, the technique is the same:

• turning the screw clockwise increases the speed/force;
• turning counterclockwise, we slow down/reduce the force.

When adjusting the closer, do not turn the screws several turns at once. Often just a quarter turn is enough, maybe a little more. Having upset the balance by tightening or unscrewing the screws too much, it is very difficult to adjust everything again. You can even break the device or cause oil to leak from inside.

Adjustments for the speed of door opening and slamming are located on the body. Most often they are either on the front part under the protective cover or on its side surface.

In round or multi-faceted housings, adjustments are located on the side of the housing

A metal entrance door is a guarantee of security.

But its negative qualities include a lot of weight, and as a result, extra noise when closing.

To smooth out this nuance, there are mechanisms, the installation of which is accessible to anyone who has a screwdriver in their hands.

So how to install on metal door? There's nothing complicated about it. Patience, a tool and a little ingenuity will help with this.

A closer is a mechanism that in most cases works according to the old principle of grandma's door spring.

But thanks to the development of technology, it was improved.

But it's not that simple. Today there are many types of mechanisms that have different usage parameters.

Which are individual for each. Depending on the scheme of supplying force to the spring, closers are divided into devices with an internal hydraulic circuit and rack-and-pinion force supply and devices with a cam operating principle.

If we consider the method of fastening, they are presented as overhead and hidden. In turn, overhead door closers are divided into two types:

• Devices with a hinged (lever) rod consisting of two elbows.
• Slider system devices – with a sliding channel.

When choosing a device, you need to take into account the characteristics of the door. Its weight and width. There is a certain scale by which the mechanism is selected; it is approved by the European standard. Door closers have 7 sizes, they are designed for door weights from 20-160 kg and door leaf widths from 750-1600 mm.

Scale for selecting a door closer

Door closer size	Door width, mm	Door weight, kg

When choosing a mechanism you need to remember the following:

• The maximum weight or width of the door is the most important when choosing.
• Installing a mechanism with underrated performance will quickly damage it.
• Exceeding the standards will lead to difficulties in closing and opening.
• If the weight or width is greater than indicated in the table, then two mechanisms are used.
• Not all door closers can be used outdoors.
• Consider the features in which the mechanism will be used. You may need a slow closing function, a locking function, or some other function. Then the closer must have such characteristics.

Studying the properties and quality of the device when purchasing helps to avoid unnecessary expenses and ensure proper operation of the device for many years.

Preparing for installation

The success of the entire procedure as a whole depends on this stage. If after the purchase the question arises of how to install a door closer on a metal door with your own hands and not use the expensive services of a specialist, first of all look in the box and find instructions and an exact drawing of the device in it. All existing door closer models include these tips.

The template shows mounting options for left and right, opening towards you and inwards. But if, for some reason, it was not in the box, then the main thing is to remember: if the door opens outward, then the main mechanism is attached to the box, and the element with levers is attached to it. And if inside, then vice versa.

The adjusting screws on the mechanism are located opposite the hinges of the door structure. The example shows all the placement methods and indicates the desired position of the holes for fixing:

• The first stage is checking the equipment according to the instructions, then preparing the tools (screwdriver, drill, drills, screwdriver, hammer and others).
• So that everything drilled holes coincided with those on the closer and for clear placement of the device as in the diagram, a marking stage is necessary.
• The closer placement template is attached to the adhesive tape. And at the site of future holes, an electric drill is used to drill in order to achieve minimal errors, a core is used, which is used to make recesses in the door leaf. It is important to remember the size of the drill, which must be selected in accordance with the diameter of the holes and fasteners. To be sure that the drill you have chosen is correct, you can drill holes on an auxiliary piece of metal and try to screw the fasteners suggested by the manufacturer into it. If the diameter is not observed, the screw may not fit or, on the contrary, may fall out, which will lead to additional difficulties during installation.

Installation

After preparing the components, tools and holes, you can proceed to the penultimate part - installation. The instructions will again help you do everything correctly:

• The closer body must be secured with screws to a prepared surface (door or slope).
• The lever system should fit into the protrusion on the bottom of the main mechanism housing and be secured with a screw.
• Connecting the lever and the rod - this process, like everything before it, is not complicated: both elements are connected, and a pressing force is applied to them. A click occurs, confirming successful alignment. But the main feature is their location in relation to. Which significantly affects the speed of closing the door structure at the last stage.
• The ability to change the location is due to two separate parts of the rod, which can be adjusted in length. The first part is represented by a long threaded strip. The rotation of this part causes a change in length.
• If you need a regular soft adjustment, place the rod at an angle of ninety degrees to the plane of the door. This is achieved by reducing its size.
• The final force to close the door (“latching”) must be strong enough to, for example, overcome the resistance of the latch or door latch. By lengthening the rod, the lever is placed perpendicular to the door structure.
• After obtaining the required parameters, the levers are fixed.
• The final touch is the snap decorative panel on top of the main mechanism.

How to install a closer on a metal door from the outside

The installation technology is the same as inside. In this case, it is not the installation conditions that are important, but the operation itself on the street. Only frost-resistant models are suitable for this. But also in them under the influence subzero temperatures, may thicken the oil in the hydraulic system.

And this will reduce the functional qualities of the door structure. In addition, the action of precipitation destroys all elements of the closer. Therefore, if it is not possible to protect it from influences or install it indoors, then it is better to abandon it altogether.

If any of the presented schemes is not suitable for installation, then non-standard fastening methods are used that will not harm the operation of the closer:

• Due to the peculiarity door frame It may be necessary to use a construction corner. It is installed horizontally using self-tapping screws. The lever structure is fixed from the inside.
• The main mechanism is installed on a construction corner, in the area of ​​the upper slope of the box. The lever is attached to the door plane.
• A specially prepared block or plate is attached to the door. They must be above a flat surface. The main mechanism is fixed to this device. The lever is attached to the box.
• An auxiliary device in the form of a plate is attached to the lower part of the slope, and the closer is placed on it. And the lever is fixed on.
• If the slope is not of sufficient size, it can be increased using a plate. A lever system is attached to it. And the mechanism itself is installed on the door according to an already known scheme.

This is a slightly more complicated installation method. It is necessary in cases where the features of the door or slopes do not allow for standard installation. This requires a little experience, and if you don’t have that, then it’s better to ask a specialist for help.

Installing a door closer on metal doors is not a difficult task that even a teenager can do. But there are times when installation requires additional skills. There are two options here. Do it by trial and error or contact a specialist.

Adjustment

The door closer installation process is complete. And for correct service all that remains is to adjust the device. The instructions include detailed item for the implementation of this activity.

As mentioned above, the adjusting screws should be located opposite the hinges of the door structure. There are usually two of them. Each of them has its own function. The first is responsible for the speed of movement of the closing structure, and the second is responsible for the last stage, the closing period, the so-called “after-clap”.

To increase the desired functions, one or both screws are rotated clockwise. When unscrewing the adjusting screws, you need to be careful; if you do this excessively, the internal oil will leak out of the device. To reduce - in reverse side. Some mechanisms may have additional adjustment elements. For example, as with a clamp or deliberate slowdown. For adjustment tools, you will need a screwdriver, with which you rotate the fastener until the required qualities are obtained.

When there is a change in temperature, humidity, or when parts of the mechanism are worn out (wear is inevitable), additional adjustments must be made. Because the closer may not perform its functions. This does not happen often, up to twice a year. The procedure is not complicated and will take up to ten minutes.

The situation is different with devices that are installed on the street. With a constant change in oil level (this occurs due to temperature differences) and exposure to snow, water, and sun rays, the closer needs to adjust its operation much more often. Up to 1 time per season. Decrease negative impact environment on the closer, devices like a visor or gutter will help.

Adjustment is necessary during use and after installing the closer. Without it, the device's functions may not function properly.

Rules for using the closer

Violation of operating conditions always leads to rapid wear and breakdown of the mechanism. To avoid this, it is important to remember the following:

• Maximum opening quickly renders the closer unusable. Some devices (slider) have a limiter, and those that do not need shock absorbers. They are mounted on the wall or floor.
• If the doorway should be long time open, then it is necessary to disconnect the lever system from the main mechanism, and then return everything to its original place. There is no need to prop the door up with anything or secure it with a rope. The closer will not last long. For this purpose, there are models with a built-in lock. Their operating principle is simple. When the door opens up to a certain point, it remains open; if it is time to close it, it must be moved to the side.
• Damage internal device occurs during forced closing of doors
• Lubricating the hinges and levers once a year will extend the life of the mechanism
• If the device is not located indoors, it must be protected from environmental influences (sun, rain). Correction of work is required twice a year when the season changes.
• Correct installation, the absence of errors in the placement of loops and other indicators will help the device perform its functions correctly.
• Once every few years is required complete replacement oil in the closer. For structures that are used outdoors at least once a year.
• Children are frequent provocateurs of door closer breakdowns because of their love to “ride” on doors. Additional load and displacement of the center of gravity cause irreparable harm to the mechanism.

The minimum service life of the device is indicated in the warranty that the manufacturer provides for its product. But for this period to increase significantly, the closer needs additional care.

Installation of a door closer is shown in the video:

To ensure that the door closes smoothly and does not frighten others by knocking, a door closer is often used. Previously, its role was played by an ordinary spring; in fact, it is present in the design of the closer and now it is only more modernized. Installing a mechanical door closer with your own hands is quite simple; such work will take no more than an hour. The main thing is to choose the right model and stock up on the necessary tools.

Before you decide to install a door closer, you need to decide on its main types and models. A high-quality device should close the door silently and very smoothly, and the person does not have to make heroic efforts to do this.

Closers differ, first of all, in their location and installation specifics. Each type of this device has its own advantages and requires compliance with certain nuances when setting it up.

There are the following types of closers:

• The upper ones are easy to install and have a fairly low price. They are usually placed on the ceiling and differ from each other in the type of traction: it can be sliding (a more expensive option) and lever.
• Floor closers are expensive and difficult to install. But they have one thing good advantage: They can be used where holes cannot be made, for example when attaching a mechanism to a glass door.
• Hidden - the most expensive and high-quality models. They are installed inside the door, so they are not visible. Can be used in door leaves with a thickness of 40 mm or more.

If the door has a closer, this slows down the process of its wear and, accordingly, extends its service life. This is due to the fact that the device partially takes over the load on door hinges and accessories.

When purchasing a device, you should also take into account the load from the door and its width. If the power of the closer is not enough for its normal functioning, two such mechanisms should be installed.

Standard diagram for installing a door closer

To correctly install the closer, you can rely on the installation diagram, which is included in the standard kit of the device. In addition to these instructions, there is all the necessary fastening and levers.

So, installation options door closer provide the following device mounts:

• Standard – consists of fixing the device on the door leaf; the door frame is used to attach the lever;
• Top - in this case, the closers are placed on the top of the box, and the canvas itself is used for fixation;
• Parallel – the lever can be located in a parallel position; a special mounting angle is used during installation.

When deciding to use any installation scheme, you should focus, first of all, on the location of the door hinges.

Using the attached mechanism installation template, you can complete the work quickly and efficiently, because all the locations of the fastening elements are already marked in it. They just need to be marked and then drilled.

To facilitate the work, the installation diagram is attached to to the right place and carefully glued along its perimeter.

When installing a door closer on the front door, you should fix it inside the room so that the mechanism is not damaged under the influence of temperature fluctuations and precipitation.

When using sliding-type levers, installation can be carried out on any side of the door leaf, even from the outside.

Self-installation of a door closer on a metal door

Installing a door closer on a metal door is quite simple if you use the template that comes with this device.

The installation instructions for the closer look like this:

1. The existing template is attached to the door in close proximity to the hinges, as well as at the top of the frame (this can be done using tape);
2. Next, all the necessary holes marked in the diagram are drilled with a drill or other tool;
3. Then the device body is fastened so that its valves, which are responsible for speed, “look” at the hinges;
4. The lever is divided into two parts, after which the side element tab is screwed to the box;
5. Next, the main lever is put on the mechanism shaft, and then secured with a screw and nut;
6. The side lever is placed perpendicular to the door frame and secured to the main lever;
7. The opening angle and speed of the door are adjusted;
8. A cap is placed on the lower part of the closer.

During the installation process, the closer should be positioned strictly perpendicular to the canvas closed door, and the speed adjustment screws should “look” towards the canopies.

Upon completion of work, be sure to check the operation of the installed mechanism. To do this, you just need to open and close the door. If difficulties arise during its operation, the closer should be adjusted again.

Adjusting and installing the door closer on a plastic door

Installing a door closer on a plastic door is also easy. In fact, the process is very similar to working with a metal door.

First, the lever is attached to the door frame, then the closer is put on and connected to the screw included in the kit. After this, the linkage is adjusted. This should be done so that the holes on the door clearly coincide with the holes in the closer. After this, you can check the operation of the door.

• If the door hits the door too sharply, you should tighten the first screw slightly in a clockwise direction;
• To speed up the door closing speed, you need to turn the same screw, but counterclockwise;
• The tightness of the fit is adjusted according to the same scheme.

When working with screws, you must be careful. Do not turn the screws several turns at once. It’s better to turn it a little and look at the result; if something doesn’t suit you, then turn it some more.

Installing a door closer with your own hands (video)

Installing the door closer is quite a simple matter. The main thing is to strictly follow all the recommendations specified in the instructions. When operating the device, there is no need to additionally “help” the door close or open faster: this may damage the mechanism. For the door to function properly, it is enough to change the lubricant of the door closer hinges every two or three years, and for the front door this should be done every year, and do not forget to change the adjustment when the season changes. In this case, a high-quality door closer will work for many years without any problems.

Before installing a door closer, the user must study the features of its design, check the kit and draw up a rough action plan for himself. The installation instructions describe all the necessary steps and list the tools that will be needed.

But there are several nuances in each stage of door closer installation that require a separate explanation. So, self-installation a hidden closer is not the best activity for someone who is doing something like this for the first time. In this situation, it is better to take the advice of a professional or ask someone who has experience to help determine the markings and other installation details.

Procedure for installing a door closer

At home, for installation on interior doors, rack-and-pinion closers with a lever mechanism are most often used - a kind of “knee” that is noticeable. Devices with slider rods are used a little less frequently. Hidden closers are used less frequently, but you cannot do without them if the installation takes place on glass structures or the interior requires strict adherence to style. There are no critical differences in the general plan for installing a door closer with your own hands.

First stage: determining the installation diagram

The installation pattern of the door closer depends on the direction of door opening. There are several types:

1. The door opens to where the door closer will be placed. In this case, the body is installed on the canvas, and the lever system is installed on the frame.
2. Opens outward from the closer. The scheme becomes the opposite - the sliding channel is installed on the moving web, and the body on the jamb.

Please note that the equipment adjustment bolts will be located towards the hinges (on the graphic instructions, find the designation in letters or numbers).

Stage two: applying the template

Included with the closers is a mandatory installation diagram, made on a scale of 1 to 1. With its help, installation of the device is noticeably easier, requiring only precise movements and certain tools. The diagram shows markings for attaching the lever and the housing.

Remember! The template always includes all options for mounting the structure - on the left or right door, internal or external opening.

The template also takes into account what classes of doors the closer is intended for, which is why the mounting location may change (when purchasing equipment, class En is chosen according to the weight and size of the door leaf). There are lines on the diagram for each type of application. different colors or types (solid, dotted).

Example of a template for installing a door closer

Third stage: step-by-step installation

Before installing the closer, the template from the kit is carefully and very accurately attached to the door leaf, following the instructions (along the lines). To do this, use thin tape. Then the centers of the holes for drilling are marked with a center punch. Next, proceed with the installation:

1. The housing is installed with fasteners, determining the correct installation by the position of the adjusting screws.
2. Then install the knee lever system on the opposite side of the door. Sometimes the parts of the lever equipment in the kit are supplied connected. The hinge needs to be removed temporarily; its installation is returned during the process of adjusting the closer.
3. Install the non-adjustable part of the lever system - the knee. To install it, use the closer axis and secure it with a nut and a key.
4. If the door closer is installed for the purpose of smoothly closing the doors without unnecessary noise, then the door closer elbow should be installed perpendicular to the door. The lever is placed at an angle relative to the blade. The door closer must be connected with the door completely closed.
5. If the purpose of installing the closing mechanism is finishing reinforcement (when using a seal or latch on the door leaf), then the rigid lever is installed perpendicular to the door. The length of the adjustable elbow is adjusted to the rigid mechanism. This installation strengthens the spring of the closer and allows for faster closing when closing.
6. The installation is completed by connecting both parts of the knee using a hinge.

The door closer installation kit includes all the necessary fasteners for installation on wooden, plastic and metal doors (if the use of the mechanism is suitable for these classes of door panels). So, screws for wood will look different from fasteners for metal.

Nuances of non-standard installation

Sometimes use is required alternative scheme installing a door closer for interior doors or heavy entrance panels. The process uses mounting plates and angles. Some models have them included, others need to be purchased separately:

• If the doorway is too deep and does not allow installing the lever bracket on the frame, then use a mounting bracket.
• Sometimes the opposite situation is possible, and the corner is used for installation together with the equipment housing.
• The design features of the door do not always allow the installation of a closer body (patterned carvings or high glass); in this case, a mounting plate is used on which the equipment body is placed.
• If the door protrudes beyond the frame or the space above the leaf does not allow attaching the closer lever, then a mounting plate is used to align the position of the body and fastening.

The choice of plate or corner will depend on the design of the blade and the size of the closer. A store consultant will help you decide.

Features of installing hidden closers

Hidden mechanisms can be floor-mounted, top-mounted, or presented in the form of hinge closers. The first type is used for installation together with glass structures, less often with plastic and wooden ones. Its installation occurs during the installation of doors. Upper hidden mechanisms require special precision in operation and extreme care. Before installing them, you need to make a special hole in the canvas into which the housing of the finishing mechanism will be installed.

The general principles of installation of such structures are similar to installing a lever-type closer with your own hands. However, not all interior designs offer this option because the fabric is too thin. Metal doors, on the contrary, turn out to be too heavy for such equipment, and the use of mechanisms with an external lever becomes the best solution.

Hinges with an integrated closer are hidden mechanisms and are designed for lightweight structures. Ideal for interior doors, completely invisible and easy to install. It is enough to use the installation diagram for conventional hidden or overhead door hinges.

Remember! Externally, a hinge with a closer is not much different from standard fittings. It only has a slightly enlarged body cylinder.

It is not recommended to install door closers on massive wooden, plastic and metal doors. The fragility of their design will cause wear and tear, which will lead to rapid failure. The traction force of such products is suitable only for the lightest fabrics.

The most difficult thing in the process of installing a hidden hinge door closer is determining the correct axis. This design is installed with a slight violation of the vertical position. If the installer has too few skills in working with such mechanisms, then it is better to use the services of a professional.

Adjusting door closers after installation

It is impossible to correctly install a door closer for entrance or interior doors without the final stage - adjustment and final settings. Primary installation does not always allow achieving proper operation equipment, which leads to breakdowns. Also, the mechanisms need periodic adjustment, which occurs during the changing seasons.

The first thing people pay attention to is the speed of the door:

• If the door opens too slowly, adjust the closer spring.
• A special nut, marked in the instructions with a special letter or number, is responsible for its compression.
• The valve head is turned, following the instructions, clockwise or counterclockwise, but no more than 2 turns in one direction.

Typically, closers have 2 adjustment valves. In rare models there is a third valve. If the first one is responsible for adjusting the speed, then the second one is used to close the door tightly - a slam. The third valve is responsible for the movement of the blade structure at angles of 90 or 80 degrees.

The hold-open function makes it possible to fix the door in the open position at a given angle (usually 90 degrees). However, not all door closers are equipped with it. If necessary, the option can be purchased along with the mechanism or installed later if necessary.

During use, many door closers need to change the oil, as it can lose its viscosity during operation and exposure to temperature changes.

entrance doors: price, device and installation features">

Top devices are considered a universal option. They are used for entrance doors to the house.For a simple installation of the closer on the front door: the lever and sliding rod are mounted on the lintel of the frame, and the body is mounted on the inner surface of the door leaf.Mechanisms with gears and lever drives are in demand. No less popular is the device with a cam gear and a sliding rod.

Hidden models are installed during the installation of the entire structure. Lower devices are mounted on the floor, which makes them practically invisible.

Helpful information! Modern options models allow you to independently regulate all existing functions.

Operating principle and design features of the closer

The device contains a lever rod and a housing with a mechanism that helps to take the closed position. The main mechanism includes a spring, which is compressed under the influence of a piston drive.

The steel spring is built into the capsule. Smooth closing of the canvas ensures special technology. There is oil inside the capsule, which, when the element moves, enters the container through hydraulic channels.

Adjustment of door closers for entrance doors is carried out using screws that are placed in the end part of the housing. The screws help change the size of the channels, which affects the movement of the oil solution.

IN modern models There is an additional pressure valve that helps to hold the movement of the blades. This design is effective in creating air resistance in the mechanism.

Some models are equipped with a motion lock feature. At the same time, spontaneous closing of the door leaf is regulated.

Helpful information! Closers can perform additional functions. This is a delay in the door movement for several seconds, dampers and coordination of the closing of the leaves.

How to choose door closers for entrance doors

Before buying a door closer for your front door, you should better study the main characteristics of the models:

• moment of inertia, which is determined by the ratio of the quality of the springs, the dimensions of the products and the dimensions of the canvas;
• The closing force is determined by the pressure that is exerted on the blade when it moves. There are 7 classes of products depending on the massiveness of the canvas;
• closing speed;
• slamming time;
• the closing delay is set individually;
• fixing the canvas.

The most important characteristic of devices is power. For street doors, stronger mechanisms are selected.

The table shows product classes depending on size and weight.

Table 1. Classes of closers depending on size and weight

Closer class	Blade width (cm)	Product weight (kg)
EN1	75	20
EN2	85	40
EN3	95	60
EN4	110	80
EN5	125	100
EN6	140	120
EN7	160	160

The following types of products are distinguished:

• in lever models, one edge is inserted into a special groove, along which the lever moves when the door moves;
• the knees are represented by two axes, which bend when moving at the knee, which ensures a smooth ride;
• gear ones differ in the effect of transmitting traction through a rack and pinion mechanism;
• The basis of the cam mechanism is a profiled cam that transmits force to the spring.

Note! If the door has a non-standard height, more than 2.5 meters, then it is worth choosing a device of a higher class.
