Vintage Kichler Lighting GI-3033 Replacement Glass Shade For K-1871 in a Frosted Trumpet Flower Pattern. PRODUCT SIZE: The Clear White Frosted Lamp Shade fitter end/the portion of the shade which goes into the lamp is 3/4 inch, 4.5 inch across fluted top, 6 inch height. WARM TIPS: Fitting opening edge is 2-1/4 inch outer, inner is 3/4 inch; Opening of shade easily fits right into the lamp socket. To avoid disappointment, please measure your current shade for accuracy. STYLE: It fit perfectly on a little upright vintage nightlight; These are not threaded and will not twist in; There is not a lip for little screws to tighten around; So it would need the type of fitter that squeezes and applies pressure to the shade. HINT: Put the bulbs in before you attach the lampshade. They are very narrow and it is hard to reach in far enough to screw in the bulbs when they are attached. The glass pieces just fit into the socket and attach easily.
