The NSI INDUSTRIES RSP-212 is a 3/4 inch cord grip designed to secure and protect electrical cords and cables at entry points into enclosures, junction boxes, and conduit fittings. Cord grips provide strain relief by clamping around the outer jacket of a cable, preventing tension from reaching internal terminations. This fitting is sized for 3/4 inch trade size openings and is installed by electricians during panel wiring, equipment hookup, and enclosure builds where cable management and strain relief are required by code.
The RSP-212 is suited for residential and light commercial electrical installations where a 3/4 inch cord grip is needed at a box or enclosure knockout. It is commonly used when connecting flexible cord or cable whips to enclosures, control panels, and machinery. Electricians and maintenance technicians install this fitting as part of NEC-compliant wiring assemblies that require mechanical protection and strain relief at cable entry points.
Designed as an OEM-style replacement or direct-fit cord grip for standard 3/4 inch trade size knockouts in electrical enclosures and junction boxes.
Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize all circuits before working inside any enclosure. Thread the cord grip into the knockout and tighten to the manufacturer-recommended hand-tight-plus specification to avoid cracking the fitting body. Verify the cord jacket is fully seated in the grip before torquing the clamping nut.
