- The Universal Interface Bracket provides a solution for simplifying inventory of RPA series mounts and SLB projector brackets.- This bracket allows for exact alignment with the projector. The projector can be shifted around on the mounting plate until its weight is centered and balanced.- The SLBO is equipped with adjustable legs and feet, which can be moved to any angle, depending on the mounting-hole pattern on the projector. Leg and foot length, width, and height can readily be adjusted.- The SLBO is shipped with All-Points™ Security System hardware, which is designed to protect projectors from theft. Chief Manufacturing provides the security kit exclusively.
