Bracket didn't fit... In two ways...
"I purchased this bracket to mount two 4.5"x10“ filter housings. The mounting holes did not line up between the housings and the bracket so I needed to drill new holes. And since the bracket is steel and powder coated, that left it open to rusting. I put on a coat of paint and covered it with washers, but still. Also, when my housings were mounted on the bracket, there was not enough clearance between the housings and the wall to attach it. So I needed to install a spacer/standoff from the wall. In all, I would have been better off just fabricating my own."
