The modular design of the ELPMB76 allows for the easy addition of a broad range of accessories for powerful added functionality. For additional truss mounting flexibility, the stacking frame attaches to the ELPMB80 Truss Adapter Bar or ELPMB78 Portrait Adapter Bar. For precise tilt adjustment, pair the frame with the ELPMB81 Tilt Adapter or ELPMB77 Tilt Adapter Plate. And for fast and precise installation of projectors that lack a zoom lens, utilize the ELPMB85 Rail Adapter for fine forward and backward adjustment of the projector distance from the screen.
