Brass Key Extensions
This Brass Key Extension is 4/36F X 4/36M (which means that it is the standard size for most threaded lamp socket stems) and is used to extend the length of a key (turn knob) through a gallery on vintage lamps like the one pictured here. These brass extensions are available in 1/2", 3/4", 1" and 1 1/4" lengths. (Length does nor include male thread.) Please indicate what size you need when placing your order.
