Uno Threaded Shade Holder

The fitter is the portion of the shade holder through which the glass lampshade actually passes and makes physical contact with the lamp. Shade holders come in different fitter sizes and so do glass lampshades. The idea, logically, is to match the same fitter size for both the shade holder and shade. Grand Brass Lamp Parts, LLC. has a large selection of Holders with UNO threading for use with UNO threaded Lamp Sockets. These holders screw onto an UNO socket.
