Rheostat Wall Mount Bracket for Single Gang Boxes

Mounting bracket for wall mountable rheostat speed controllers.  Allows rheostats to be mounted securely into common single gang boxes.  The top and bottom holes line up to the top and bottom mounting holes on the gang box and an additional hole acts as grounding screw hole if needed.  Most speed controllers do not require grounding, since they are simply inline voltage regulators.  Grounding screw IS included.
