NOTE :
Some commonly thought to be doorstops are not doorstops at all but Doorstop Lamps.

The Critical Characteristics of a Doorstops Lamp is that they look like what we know as a well known doorstop from the Front. However, they always have a U-Groove on the back to hold the Electric Bulb.

This U-Groove holds a Hollow Threaded Rod secured by 2 nuts that sandwich this metal projection. The Light Scocket screws onto this threaded rod and the electric chord goes thru the hollow part of the rod & plugs into the wall. Probably, the main reason these get confused with actual doorstops is that usually the Threaded Rod, the Bulb & the Electric Chord are missing and the only distinguishing feature is that U-Groove protuding from the backside
