We have had a number of 4 tube florescent light fixtures installed in the basement since sometime in the late 1960's.
One of the "shades" recently decided to crack and break for whatever reason. The replacement shades that I can find are all about 1/4 inch to wide to allow it to sit flat within the frame for the light fixture.
Given the thickness, or lack thereof, I can't seem to trim it to fit. Everything I've tried results in a shattered shade.
Help.
