It’s got a 4.5†full diameter, might be normal for these kind of things but I’m not an electrician so I didn’t expect that and it’s too big for my electrical box, 4 stars because of painless return. Please add the full diameter to the description for DIYers

This knock-out seal is for a nominal 2-1/2" conduit hole, but fits an actual measured 3" sized hole. I had a 3" hole in some sheet metal and this fit perfectly.
