Doorstop

A doorstop (also door stopper, door stop, door wedge, door check) is a device that holds a door open or closed, or that limits its swing. It may be a wedge or heavy object on the floor, a bumper attached to a wall or floor, part of the hinge or door closer, part of the door frame, or a bracket attached to the door frame.

In this case a rubber cylinder or dome—or a rod or block of rubber-tipped metal, wood or plastic—is screwed into the wall, molding or the floor in the path of the door. If it is attached to the wall, it may be either a few inches above the ground, or at such a height as to meet the doorknob. A short, wall-attached doorstop, usually a rubber dome or cylinder, is sometimes called a wall bumper. Rigid metal springs (also tipped with rubber or plastic) are used to absorb and more widely distribute the kinetic energy of the door swinging. On occasion, stops are used that are fitted at the midpoint of the door, as part of the central door-hinge. Such stops are known as a "hinge stops" or "hinge pin" doorstops and are often used to prevent damage to baseboard molding.
