Those fluorescent fixtures with the 2" ko's at dead center tend to really irritate me when I am planning to directly enter the fixture,oops luminaire, with a romex cable at the center of the fixture. I don't see the fixture until trim, so didn't plan for it to have such a big ko right where I want to send my wire into the fixture. On some of the ones supplied to me, trying to unibit a1/2" ko into the 2' ko is a joke, it will practically fall out in its entirety.
