door check
Hinge-mounted speed control
A door check is a device that controls how a door opens and closes, preventing it from swinging too wide or slamming shut.
On cars, the door check is the mechanism that holds the door at fixed positions when open: The door check was worn out, so the door wouldn't stay open on hills.
On buildings, door checks are typically hydraulic or pneumatic closers mounted at the top of the frame.
