The Chief CMA370 Unistrut Adapter is a small hardware kit for installers who need to fasten a Chief ceiling plate to strut channel instead of directly to wood or concrete structure. Many commercial ceilings use Unistrut or similar 1-5/8 inch (41 mm) channel to bridge between beams or to create an attachment grid, and this kit gives you the spring-loaded channel nuts and bolts to lock a Chief plate onto that channel securely.
The kit includes four 0.38-inch (10 mm) channel nuts with springs, which drop into the channel opening, rotate into place and hold position while you line up the plate, plus the attachment bolts. Chief rates the assembly at 250 lbs and lists the kit as TAA compliant. The ceiling plate, strut channel, column and mount are not included, so plan those as separate line items.
