The sample kit is the place to start. It made it apainless process to identify the lens that would work with my light fixture.
Easy to install and unavailable in big chain stores like Home Depot & lowes
I bought these to replace broken shades on fixtures installed in the 1980’s. The clasps on the fixtures needed to be adjusted slightly but the end result was great. Good price and very quick standard delivery.
Works great, and was easy to install on my own.
Thoroughly satisfied with my desk protector
