Overview

The NSI Industries SB-383NM is a patented D721,652 split bushing designed for 1-inch trade size Rigid/IMC conduit. Unlike traditional bushings that require burning or pullers, this nylon plastic bushing installs after wire pulls, saving installation time and effort. Its split design allows retrofitting without disturbing existing wiring, making it ideal for upgrades or complex installations. Engineered for 105°C operation and cULus listed to UL-514B, the SB-383NM provides a smooth, protective barrier at conduit entrances, junction boxes, and raceways. The 0.86" x 0.57" x 1.05" x 1.60" dimensions (A x B x C x D) ensure compatibility with standard 1" trade size systems. The high-quality nylon construction resists wear and tear on conductors, enhancing electrical system safety and integrity. With a standard package quantity of 250 units, the SB-383NM is optimized for bulk procurement in electrical contracting and maintenance operations.
