The VMP SCM-1 Suspended Ceiling Adaptor lets you mount a projector or display from a drop ceiling by resting a steel tray on the ceiling grid. It works with 2 ft by 2 ft or 2 ft by 4 ft tiles and accepts a VMP ceiling mast or standard 1.5 inch NPT pipe, so you only need to cut a hole in the tile for the mast to pass through. The tray supports up to 75 lbs and the mount position can be set anywhere along its full length.
