The nVent CADDY Heavy Duty Telescoping Bracket Between Stud Assembly line increases overall productivity, savings, and job site safety. For ultimate flexibility, the assemblies are configured with the most common box and mud ring combinations. The line is also offered in both standard and open back boxes as well as in single and double gang fixed or adjustable depth mud rings. When paired with the nVent CADDY Open Back Box, the assembly is ideal for prefab installations where devices, fittings, and cables are installed to quickly and easily complete make-up wiring connections, without the need to drop or work through the mud ring.
