Concave vs. Convex Wall Stops

Wall and floor stops are inexpensive products that, when installed correctly, can help prevent damage to a wall, lockset or door. If a door is forcefully pushed open, a stop is meant to protect the wall from being gouged by the door or lockset, and it will also protect the door hardware from being damaged by a quick meeting with the wall.


Wall and floor stops come in a wide variety of shapes and sizes and can be mounted on the wall or on the floor behind the door.  For this post, we are going to focus on concave and convex wall stops.

First up convex. The definition of convex from states:  “having a surface that is curved or rounded outward.”
A convex wall stop looks like it is made out of half a rubber ball with a piece of metal surrounding it.



The concave definition is: “curved like a segment of the interior of a circle or hollow sphere; hollow and curved.”
A concave wall stop has that same rubber ball style but has an indentation right at its peak. This indentation accommodates the thumb turn or button on the latching hardware.



If you’ve ever come across a damaged lockset where the locking button has disappeared into the handle, look at the stop. It will either be a convex type or missing altogether. There may also be a corresponding divot in the drywall, or the tile may be cracked.

As noted earlier in this post, there are many different design choices for wall stops. Check out our entire line here to find the style that best fits your needs.
