Some rigging hardware must be attached with threaded fasteners, such as AMFS Truss Modules and BumperWare models. If the cabinet has recessed pans, use the 12-Jaw fitting with threaded studs to lock the frames firmly into place. This fitting raises the mounting plane by 1-1/16A″ and a locking style nut and washer is included. Its double redundant lock makes this an ideal lifting device for overhead suspension.
