Public address speakers hang from overhead structural framing girders using Unistrut P1001T channels secured with P2786 beam clamps in four places. Four half-inch threaded rods with rod stiffeners support an Adaptive SAS-48-RB frame carrying the speaker units. Each speaker weighing up to ninety pounds attaches to the frame with 3/8-inch hardware and features a 40-degree adapter bracket along with three lengths of 3/8-inch wire rope with shackles tied to rigging eyes. Four 1/8-inch diameter wire rope braces at ten to forty-five degrees stabilize the assembly against lateral movement.
