Ok its 1in that I used then I used electrician nut on nipples after burning them. Just because.
Jethro, 1" is a tight tight fit. Best to use a step bit for the best fit. I'm an electrician and it is standard practice to use 1 1/8" hole saw to pass a 3/4" conduit through any hole but this is with a tiny bit of play. So 1" - 1 1/8" works for OD. 7/8" hole is for 1/2" conduit.
