The nVent CADDY RS Retrofit Retainer Strap is designed to assist in the securement of beam clamps and other flanges to metal structures. Due to the post-installation function, the RS Retrofit Retainer Strap can be added to pre-existing hanging systems without dismantling any clamps or threaded rods already in place. With a teardrop-shaped opening to lock onto the rod, contractors can be confident that components will not shift during installation and will retain their integrity even in the case of a seismic event.
