I had a basic light fixture mounted in my garage ceiling. I'm putting a ceiling fan in its place. After removing fixture, there's a square box with 3 conduit connections. I undid the connections and cut ceiling around box. I used a hammer and pry bar to get the box out. It was nailed to the joist.
I thought I was home free until I looked at the new ceiling fan box with the adjustable bar. Box only has two knockouts. I went online and it seems that all these boxes either have one or two knockouts.
What do you suggest? I want to make sure the box I put in is up to code, whatever that is. Thanks.
