I'm installing recessed LED fixtures in a room and I'm almost done but one of the junction boxes won't fit on the ceiling because the old metal box was at a cross section between two wood beams. I've done some research and I'm pretty sure it's a furring strip that is meeting one of the structural wood joists.
I want to trim away / cut into the furring strip so that I can squeeze my junction box on top there. Is there anything wrong with this? My understanding is that they're just there to further support the drywall ceiling, right?
