Upgradelights Harp and Slip Uno Adapter for Lamp Using Uno Euro Fitter with 1-7/16 I.d.

Slip Uno adapters are made to fit directly over a plastic lamp socket. This kit includes both the adapter and the harp. Then it will allow you to use nearly any replacement shade on that lamp. This is meant to be an alternative to the lampshade which has fitter already attached to it. The opening on this adapter is 1 7/16". A plastic washer (ring) is needed to hold the adapter tightly in place. Please note there are two fitter sizes (1 7/16 and 1 9/16 inches).
