The Chief CMA366 Architectural Spanning Adapter lets you hang a projector or flat panel mount from exposed truss, pipe grid or similar overhead structure where there is no solid ceiling deck to bolt into. Instead of attaching to a single member, the adapter spans across two parallel chords and clamps to each one, creating a centered, load-rated attachment point for a 1.5-inch NPT extension column.
The clamps grip round tube up to 2 inches outside diameter or square tube up to 1.9 inches, and the span adjusts from 5 to 18 inches to suit common truss profiles. The mounting point can be shifted laterally so the column lands exactly where the display or projector needs to hang, and cabling can be routed down through the column for a clean drop. Chief rates the adapter at 250 lbs and lists it as UL Listed and TAA compliant. The column, projector mount and display are sold separately.
