This isn't exactly electrical but it does have to deal with electrical components of the home.
I need to replace a light shade that is hanging over my kitchen table. I know that it is a neckless shade. Although the tape measure isn't perfect because I was trying to hold it and the camera at the same time, the fitter size should be between 1-1/4" and 1-1/2". Does this mean that I need to purchase a 1-5/8" fitter sized shade?
