What is a door closer?

A door closer is a mechanical device that is typically mounted on a door to automatically close and secure it after it has been opened. Door closers are commonly used in commercial buildings, such as offices, schools, and hospitals, to ensure that doors are properly closed to maintain security and energy efficiency.

There are several types of door closers available, including surface-mounted closers, overhead closers, and concealed closers. Surface-mounted closers are the most common and are mounted on the surface of the door and frame. Overhead closers are installed on the top of the door and frame, while concealed closers are hidden within the door and frame for a seamless look.

Door closers can be adjusted to control the speed at which the door closes, as well as the amount of force required to open the door. This is important for ensuring that the door closes properly without slamming shut or causing damage.

In addition to providing security and energy efficiency, door closers also help with accessibility for individuals with disabilities by ensuring that doors can be easily opened and closed. Some door closers are designed to meet ADA (Americans with Disabilities Act) requirements for accessibility in public buildings.

Overall, door closers are an important component of building security and efficiency, providing a convenient and safe way to control the opening and closing of doors.
