5 Pieces Automatic Door Closer

A door closer is a hydraulic device that is used to automatically close a door after it has been opened. Door closers are commonly used as a fire prevention measure, typically installed on fire doors, as well as helping to prevent draughts.Surface-mounted door closers are the most common type, as they are comparatively cost-effective and easy to install. They are fitted to the door frame behind the door, next to the hinge. The arm of the closer retracts to closed configuration as the door closes.As well as the standard, double-lever arm, there are different kinds of arms available for surface-mounted door closers, depending on the application and to provide more functionality.The mechanism of door closers ensures a controlled closure of the door. The damper feature keeps the force and speed of the door closure at a certain level. This is important when it comes to heavy doors and people who are vulnerable to injury.
For example, door closers prevent injury to small children and to differently-abled persons who might not be able to resist the weight of the door. Anyone who can't move quickly enough can experience the pain of pinched fingers. People with heavy cargo, like multiple bags, can also benefit from door closers.
