Overview

The NSI Industries RSR-105 is a heavy-duty aluminum cord grip designed for liquid-tight sealing and strain relief in industrial applications. This 1/2" NPT threaded fitting accommodates cable diameters from 0.250" to 0.312" (6.35mm–7.93mm) and is available in Form Size 2 with a gray nylon body, rubber grommet, and zinc-plated steel compression nut. The liquid-tight seal meets NEMA Type 6P standards when used with the included neoprene O-ring and locknut, providing protection against dust, water, and corrosive environments. The grommet is color-coded for quick identification of cable size compatibility, and the nylon washer ensures a secure, vibration-resistant connection. UL File No. E76954 and CSA File No. LR32159 certified, this cord grip is ideal for enclosures requiring reliable cable strain relief in harsh conditions, including outdoor or washdown areas. The aluminum construction resists corrosion, while the rubber grommet offers chemical resistance and temperature stability from -40°C to 105°C.
