I have to give an estimate on installing ceiling fans in a church. There is a drop 2x4 ceiling about 3' below and old wood ceiling. They want the fans to hang down about 2.5' below the drop ceiling. I would appreciate any suggestions on suspending these and also how to stabilize them. I am assuming that I would have to go to the wood ceiling for support. Is there any hardware out there that would work well in this situation?
