door closers
Automatic shutting devices
Door closers are mechanical devices that automatically close a door after it's been opened.
The most common type mounts at the top of the door frame with an arm that controls closing speed and force.
They're standard in commercial buildings for fire safety and accessibility compliance.
The door closer needs adjustment—it's slamming too hard.
