The NSI INDUSTRIES RSP-211 is a 3/4-inch cord grip designed to secure and protect electrical cables at entry points into enclosures, junction boxes, and conduit fittings. Cord grips of this type provide strain relief, keeping conductors from being pulled or stressed at connection points. The RSP-211 is a grip-only unit, meaning it does not include an integrated connector body, making it suited for installations where a separate fitting or bushing is already in place. Licensed electricians and maintenance technicians install this type of hardware during panel builds, enclosure wiring, and service work on industrial and commercial electrical systems.
The RSP-211 is applicable to residential, commercial, and light industrial electrical installations where 3/4-inch cord grip strain relief is required. It fits enclosure knockouts and threaded fittings sized to accept a 3/4-inch cord grip. Typical use cases include securing flexible cord and multiconductor cable at control panels, motor starters, and electrical enclosures where physical protection of the cable entry point is required by code or best practice.
Designed as an OEM-style strain relief cord grip for use with 3/4-inch electrical enclosure knockouts and threaded fittings in standard commercial and industrial wiring applications.
Installation is typically performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and lock out the enclosure before beginning work. Ensure the cord grip is fully seated and tightened to maintain proper strain relief without damaging the cable jacket. Do not overtighten, as this can deform the cord and compromise insulation integrity.
