The black PRG Precision Gear Projector Mount from Peerless Industries is a ceiling mount for digital projectors weighing up to 50 lb. It features a precision gear mechanism that ensures accurate image alignment. Two adjustment knobs control this mechanism, and an integrated cable management system helps keep cables out of your way. The mount features a quick release mechanism, allowing you to easily unmount the projector for maintenance. The quick release is designed so the projector retains its registration, eliminating the need to realign the unit after service.
