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.
