Doorstop

Device to prevent door from moving, or opening too far

A doorstop is an object or device used to hold a door open or closed, or to prevent a door from opening too widely. The same word is used to refer to a thin slat built inside a door frame to prevent a door from swinging through when closed. A doorstop (applied) may also be a small bracket or 90-degree piece of metal applied to the frame of a door to stop the door from swinging (bi-directional) and converting that door to a single direction. The doorstop can be a separate part or integrated with a hinge or door closer.
