nVent CADDY TDH hangers from nVent ERICO area quick and easy way to attach fasteners to metal decking. Just use the TDHP2 decking hanger punch to put holes in the decking, line up the hanger and slide the retaining bar through the holes. It's that simple. The hangers are ideal for suspending lights and hanging cable tray, dropped ceilings and strut trapezes from overhead metal decking. They are constructed from spring steel, which is durable, lightweight and has high gripping power. As shown on the following page, TDH decking hangers are fully rated to hang loads from roof decking, unlike screws, which are not load rated, evaluated, or approved to support vertical loads from roof decking. The TDHP2 decking hanger punch has been redesigned to include more features. The improved punch can be adjusted from 12 mm to 80 mm according to individual requirements. Press-fit ejector springs allow for easier removal of the 1-piece hole punch after the punching operation is completed. The hardened and tempered punch is easy to operate due to the smooth-running, patented transmission mechanism.
