The CADDY 6QCNR2 Rod Lock Strut Nut is engineered for fast, tool-free installation onto 3/8-inch threaded rod, making it ideal for electrical, HVAC, and plumbing support systems. Featuring push-to-install technology, this spring steel nut snaps securely into place-even on rods with minor burrs or damaged threads-eliminating the need for traditional spring nuts or loose hardware. It's compatible with standard strut widths (1-5/8 in.), including shallow and deep profiles, and can be used with hex nuts or truss head bolts for mounting enclosures, trapeze systems, or branch runs. This 2-pack offers a durable, corrosion-resistant solution for contractors seeking speed and reliability on the job site.
