The CADDY 8QCNR2 Rod Lock Strut Nut offers a fast, tool-free solution for mounting to 1/2-inch threaded rod in 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 and loose hardware. It's compatible with standard strut widths (1-5/8 in.), including shallow and deep profiles, and works with hex nuts or truss head bolts for mounting enclosures, trapeze systems, or branch runs. This 2-pack delivers a durable, corrosion-resistant solution that saves time and simplifies installation for contractors and installers.
