- Choosing a closer
- Installation of the mechanism
- Regulation of the product
After all, they ensure the correct operation of locking mechanisms, respectively, the doors are closed quietly and smoothly.
Design of devices 
The popularity of such devices is due to the benefits:
- functionality;
- security of continuous use.
In addition to self-locking design, the closer for the entrance door ensures the protection of the room from the inside, the external noise and the environment minimally affect the internal atmosphere. Improved thermal insulation and the absence of drafts allow you to save energy.
Security is guaranteed only when the closer is properly installed on the door and, accordingly, configured according to the instructions and the technological map.
The typical closer consists of a housing and device lever thrust. The door closing occurs due to the presence of a spring in the mechanism, under the action of the piston, it shrinks. There is a spring in a special capsule, which is filled with technical fluid. This oil is removed from the capsule along the hydraulic channels, returning the spring to its original position. This element in the mechanism is selected depending on the weight and other doors characteristics.
For the correction of the mechanism, after proper installation of the door closer, there are special screws on the case, their adjustment allows you to set the optimal closer mode. Advanced device models, so-called automatic door closers, have an additional valve that is responsible for the smooth travel of the canvas and its tight closing it with the oral.
Choosing a closer 
The market offers enough device models, so it is worth it to get acquainted with the information offered.
Availability of additional functions
Among the mechanisms are offered an electric door closer, which is an automatic drive for its opening-closing. Mainly in such devices there is a whole set of additional functions, such as connecting different sensors.
Important criterion manufacturer
But first of all, when choosing the necessary closer, pay attention to the manufacturer, European and Japanese companies produce very high-quality products. Chinese analogs are better not to be considered as an option, because for the assembly of the mechanism, poor-quality metal is used, respectively, the device is short-lived. The spring is rapidly wear out, the oil constantly follows, the regulation of such closers ceases to be possible. Optimal manufacturers guaranteeing the quality of their products:
- Ryobi;
- Geze;
- Dorma;
- Cisa.
Features and performance
Next is to choose the item on the characteristics, the instructions on the door closers presented the main indicator - power design or its size. By European standards the notion of the size of the door closer implies a certain spring force. On sale are offered closers EN1-EN7, they are designed for canvas up to 2,5m. For example, EN3 are suitable for door width up to 95cm and a weight of not more than 60kg. When you select a larger mechanisms should take into account wind resistance.
To help handyman offers not only advice but also a training video installation latching the door. This example clearly gives to see all the intricacies of the process and memorize the algorithm necessary actions.
Mounting mechanism
For independent of the work there is a special instructions for installing door closers, it helps to cope with all the nuances of the process. Depending on the installation method, there are three types of structures:
- bottom or floor;
- upper;
- hidden.
Sometimes, for certain types of doors are used at once two constructions, in this way ensuring a long and high-quality work mechanisms.
Setting the first type of construction 
Lower or outdoor unit is provided still in the process of building design, because the installation of the door closer scheme involves breaching a niche in the floor. This depression is located directly under the door structure, the basic requirement of a successful installation - it is appropriate instructions and match the output device with the stem axis hinge leaf. This is closer to a plastic door, as well as mechanisms are widely used for glass doors in shops and offices.
The most common installation method 
In most door closer fixed to the inner upper portion of the web, because it provides some protection device for long-term use. To carry out the installation of door closers need:
- scheme;
- device;
- lever arm;
- fasteners.
The tool will need:
- screwdriver or screwdriver;
- drill;
- hammer;
- adjusting key.
Set closer to the door is easy, just run:
- markup. It operates according to the pattern instructions from the manufacturer, the angle is calculated for this structure opening. In the present pattern spaced holes, so it is sufficient to attach the attached sheet in full size and transfer mark;
- holes in the designated areas, they are drilled using a drill;
- fastening the unit case on the canvas screws required diameter;
- the installation of the mechanism into the perpendicular position with respect to the door box is so adjustable the length of the sleeve. This allows you to set the desired door opening angle;
- sturdy connection of all device elements.
Such products are universally installed, this is the perfect door closer for metal doors. Apply at the entrances to various offices, residential entrances and office space.
Hidden mechanisms
All elements of the hidden closer are mounted in the canvas and the door frame, when opening is noticeable, the only element of the device is noticeable. But when choosing such a closer, it is worth considering the thickness of the door, it should be more housing thickness. To provide small dimensions, a cam mechanism has been developed, it transmits a traction force from the spring to the input rod. The hidden closer is designed for interior doors, except for installation on a fragile glass design there is the possibility of mounting on a regular wooden model. The popularity of such devices is limited due to the high cost of products and installation.
Regulation of the product 
After installing the closer, the door will need to configure the mechanism, it will require certain design knowledge and a conventional screwdriver. Despite the peculiarities of the device, the adjustment of the stroke or the edge is carried out by rotating the posed nuts, screws and valves.
- To adjust the door closing speed in the design, screws are offered, according to the instructions, as a rule, it goes screw1. Its rotation clockwise reduces the closing speed, twisting - increases.
- Control speed adjustment is provided by screw2, the principle of action is the same.
- Opening the door can also be corrected - it is possible to relieve a difficult course by unscrewing the adjusting nut, and it makes it difficult to turn the nut clockwise according to the rotation.
- The opening angle varies with the valve, it is also rotated in the required direction - either to increase or decrease.
