If you want to mount our popular ceiling boxes in a drywall ceiling, you need the "FRAME". The "FRAME" is used in conjunction with the FSR ceiling boxes. The ceiling boxes and frames can be used anywhere you need to mount equipment in the ceiling, or where you are mounting a projector or display in the ceiling.
The CB-SR12 drywall mounting frame is designed to easily mount FSR's 1'x2' (CB-12) Ceiling Enclosure. The mounting frame can be installed in the ceiling using threaded rod, stranded wire cable, or screws through specific holes in the sides of the unit. The ceiling box can then be hung vertically, via the included cables, while the equipment is mounted and wired allowing convenient access to the components and cables.
