Lamp Socket Key-Turn adds decorative appeal to lamp restorations. Use to replace plastic turn knob switches. Simply unscrew plastic turn knob and replace with decorative key-turn. Fits most standard lamp sockets, however does not fit mogul or fat boy sockets.
I got the key-turn to put on the 4" adjustable candle socket, but there's a gap between the end of the key-turn and the threading, and the threaded post on the socket wasn't long enough to reach it. I was able to make it work by filing down the end of the key-turn and it looks very nice.
