The Chief CMA290 is a pack of ten wire suspension locks for hanging equipment from flexible wire rope instead of rigid pipe. Each lock uses a one-way clamp that lets the wire feed through in one direction and grips it against the load, while a quick-release lever lets the installer reposition or level the hung device. The locks accept 0.13-inch (3 mm) or 0.19-inch (5 mm) diameter wire rope, and Chief rates them at 250 lbs on the smaller wire and 640 lbs on the larger. Wire suspension is useful for signage, speakers, lightweight displays and secondary safety lines where a column is impractical. Wire rope, ceiling anchors and device hardware are not included, and the full system must be rated for the load. Chief lists this item as not TAA compliant.
