Rockfon® 495 Facett™ Clip is an acoustical tile and suspension system accessory that installs over the main runners and cross tees to hold down acoustical panels. This accessory can be used with all Chicago Metallic™ grid suspension systems and is used when positive retention on acoustical panels is needed. This two-part clip installs by snapping the sheet metal bracket over the bulb of the grid. Squeeze the wire form together and insert into the bracket. Push the wire form down the ratchet feature until the wire form puts pressure on the back surface of the panel.
