I have this Telehook mount that I'm initially going to use with a 42" LCD. My problem is that it has a circular mounting bracket that is wider than the beams (joists) that I can attach it to. So I'm try to figure the best way around this. The beams are 2x12's that are 12" on center. So I'm thinking about cutting 2 10" pieces of 4x4 and using 4" screws to bridge 2 of the beams. Then I'll bolt the bracket into the 4x4's. Any other ideas?
