Door closer to the door

A door closer is a mechanical device mounted on a door, whose main task is to automatically close the door when it is opened. It is widely used in public buildings, offices, as well as homes to ensure that doors are not left open unattended.

It works on the principle of a spring or hydraulic system that generates a controlled force, closing the door smoothly and evenly. The door closer can be equipped with various adjustment mechanisms to adjust the speed and closing force.
