Overview

The RSR-209 cord grip from NSI Industries is a heavy-duty aluminum strain relief fitting designed for 3/4" NPT threaded entries. This Form Size 3 unit accommodates cable diameters between 0.500" and 0.562" (12.70–14.27mm), providing secure strain relief and liquid-tight sealing for industrial applications. Constructed with an aluminum body, stainless steel mesh collar, and rubber grommet, the RSR-209 resists corrosion and withstands harsh environments. The 50% double-weave stainless steel mesh improves pull-out resistance and cable protection, making it suitable for both indoor and outdoor use. Certified to UL File No. E76954 and CSA File No. LR32159, this fitting meets NEMA 4 wet location requirements and hazardous location ratings (Class I, II, III Divisions 1 & 2). The zinc-plated steel nut and neoprene O-ring ensure a reliable seal, while color-coded grommets simplify identification. Ideal for enclosures, control panels, and machinery where cable strain relief and environmental protection are critical.
