3-1/2" Round Vapor Box With Adjustable Bracket, Depth: 2.65", Non-Metallic

Just like our vapor boxes for fixtures and devices, these fan/fixture boxes have built-in flanges with gaskets installed that form a protective barrier against air infiltration, so installers can meet residential codes where required. Best of all, they deliver flush ceiling installations! Fast, secure installation in new construction, our fan/fixture vapor boxes mount to wood joists with supplied screws.
