The uno lamp shade can be mounted on a lamp socket with an uno fitter. The uno fitter’s arm radiates outward to the inner edge of the lampshade, supporting to a round piece that slides over the socket.
- Types. Uno shades are threaded and non-threaded as well as plastic and metal fitters.
- History. Traditionally, threaded uno fitters were widely used by floor lamps with an extended arm and a downward pointing socket. Now, uno lamp shades are used by many imported lamps with standard orientation.
- Tips. Sometimes, uno lampshades are not interchangeable. While choosing shades and bases, you need to pay attention to the size of the opening, the length of the arm, and the presence or absence of the line.
- Terms. Fitter means the central piece that fits onto the lamp socket. Spider means the arms radiating outward from the fitter that attach to the shade.
- Benefits. You can place a shade on a lamp without the added hardware of a harp or finial.
- Warning. Over time, the threaded uno lampshade assembly will wear out, making the shade sit shakily on the electrical socket. This can cause a fire. Besides, lamp will easily fall over if the shadow is bumped into.
