Commercial door stops come in many variations. However, one of the most common type of door stop used is the wall stop.

A wall stop is mounted to the wall at the height needed to come into contact with the lever or trim on the door. Because the lever on the door comes into contact with the wall mounted door stop there is something very simple to consider when ordering a wall stop.

Concave VS. Convex

What is concave and what is convex? You may wonder why the difference even matters.

A wall stop that is concave will have a cavity in the protruding rubber stop portion of the stop.

A wall stop that is convex will have a rounded rubber stop that protrudes out of the stop.

So why is this important to consider? A lever on a lock set can have a push button that, when pushed in, will lock the lever. The concave wall stop will allow the push button on the lever to fit inside the hole, thereby preventing the button from being pushed in and accidentally locking the door.

A concave stop, on the other hand, would be used for doors with non-locking hardware such as passage levers or pull handles.
