What does UNO fitter and UNO Holder mean?
Occasionally fabric shades will have “UNO fitter” hardware that is designed to screw onto a standard lamp socket. Our fabric shade descriptions will specify UNO fitter if they have the UNO fitter hardware. The UNO fitter is located in the center of the metal tripod spider, which is located in the top of the shade. The shade’s UNO fitter has threads and is designed to screw onto a lamp’s socket (provided the socket has threads on the metal outer shell). See UNO fitter below, shown on a bridge arm lamp.
