How to Use an UNO Shade Adapter

Every lamp shade has a fitter: the way the shade connects to the lamp. Glass lampshades are separated by the their fitter size and fabric lamp shades are separated by their fitter type. Example: a 6 inch fitter glass shade can have a variety of style shapes and sizes but it connects to the lamp with a 6 inch shade holder and a bulb clip fitter fabric shade connects to the lamp by clipping onto the bulb. Common fitter types for fabric shades include washer fitter, bulb clip fitter, and uno fitter. In this article we will explore the use of the UNO type fitter and the UNO fitter adapter.
