What does washer fitter mean?
Many fabric and paper shades have a washer fitter. The washer fitter is located in the center of the metal tripod spider, which is located in the top of the shade. The washer fitter is shaped like a washer and has a 7/16″ diameter center hole, which allows the washer to slip over either a ΒΌ” diameter rod or 3/8″ diameter rod. (Most lamp harps have a 1/4″ diameter (1/4-27 M) and some lamp cluster bodies have a 3/8″ diameter (1/8; IPS rod) located on top of the harp or cluster). Usually a finial is screwed on top of the rod to lock the washer fitter of the shade down firmly. See washer fitter below. Click here to view our extensive selection of lamp finials.
