Overview

The NSi Industries 3501-US 3/4" Steel Rigid Conduit Set Screw Connector is a Made in the USA solution designed for secure, reliable connections in rigid conduit systems. Constructed from hardened steel, this connector ensures a tight, vibration-resistant fit with its captive hex head set screw, eliminating the need for conduit threading. The nylon insulated throat reduces wire pulling effort by up to 50% and prevents first-thread damage, meeting and exceeding code requirements for bushings. Certified by U.L. (File No: E-23018) and CSA (LR-2884, LR-4484), this connector is suitable for concrete-tight applications and can carry ground fault currents up to 10,000 amps RMS. Finished with electro zinc plating and chromate coating for superior corrosion resistance, the 3501-US is ideal for industrial facilities, electrical contractors, and construction projects requiring robust, compliant conduit connections. NSi Industries’ precision engineering ensures long-term performance in harsh environments.
