The mounting frame can be installed in the ceiling opening 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. The ceiling box can then be lifted into the frame and locked into place. The ceiling box interior can be accessed in the same way for future re-cabling and service.
