The Universal Projector Mount fits most projectors under 25 lbs and features four double-jointed support arms that allow flexible positioning to reach almost any mounting point. Each arm can be precisely positioned to avoid covering important projector ventilation and access points used for lamp and air filter replacement. This minimizes heat build-up and maximizes lamp life. Unique leveling barrels allow the PBL-UMS to adapt to any projector base, no matter how oddly shaped, to maintain a level installation. Its robust construction allows the mount to positively hold the projector fixed at nearly any angle
