The nVent CADDY Rod Lock family of products allows contractors to prefabricate complex assemblies at ground level or off-site, and then install by simply pushing the threaded rod supports into the Rod Lock device. This ingenious technology works with threaded rod with burrs or imperfections, helping to eliminate clean-up time or the need to replace damaged threaded rod.

The most unique feature of the system is its breakthrough "push-to-install" design, which dramatically reduces the installation time of threaded rod support structures when compared to conventional fasteners. Simply speaking - Rod Lock is revolutionizing how contractors support conduit, cable tray, lights, ductwork and pipe by helping to make installations faster, easier and more secure.
