The Strong™ SM-PROJ-L-BLK is a sleek, robust design that features adjustable arms to fit most projectors weighing up to 50 lbs. You'll appreciate the simplicity of the system, as well as the flexible mounting options and low-profile look. For the most versatility in your next projector installation, this mount features arms that extend for up to 16-7/8" diameter mounting, rotatable joints for hole specific location, and horizontal & vertical adjustable mounting tabs (up 1-1/16" drop). Low-profile mounts have the advantage of keeping the projector tight to the ceiling, but there are still times where integrated wire management is needed. Our ceiling plate takes care of those wiring challenges and delivers a clean, finished install. With 11.5 threads per inch, this projector mount will work with any poles using a 1.5" NPT.
