Abstract
A wall door stop includes a pin extending from the wall-facing surface. When installed on a wall exterior, the wall door stop may be attached by a regular or security screw to the wall. The pin engages a mating hole in the wall and inhibits unauthorized removal of the wall door stop through rotation and simultaneous pulling of the decorative ring. The pin engages the wall to prevent rotation of the decorative ring.
