Overview

The NSI Industries RSR-731-E cord grip is a heavy-duty aluminum strain relief fitting designed for 2-1/2" NPT threaded openings. This industrial-grade cord grip features a stainless steel mesh collar with a 50% double weave construction, providing superior pull-out resistance and cable protection in demanding environments. The aluminum body ensures corrosion resistance, making it suitable for both indoor and outdoor applications, including NEMA 4 wet locations when paired with the appropriate gasket. Key specifications include a cable range of 1.812" to 1.938" (46.02mm to 49.23mm), a threaded NPT size of 2-1/2", and a construction consisting of aluminum threaded body, compression nut, mesh collar, rubber grommet, and zinc-plated steel friction ring. The stainless steel mesh is designed with a half double and half single weave pattern for optimal flexibility and durability. Hazardous location ratings include Class I, Division 2; Class II, Divisions 1 and 2; and Class III, Divisions 1 and 2, ensuring compliance with stringent safety standards. Ideal for securing and protecting cables in industrial control panels, machinery enclosures, and electrical installations, the RSR-731-E provides reliable strain relief and liquid-tight sealing. The robust design minimizes cable stress and prevents moisture ingress, reducing the risk of electrical faults and downtime.
