Overview

The NSI Industries N178 (104-S) is a UL Listed steel-zinc conduit locknut designed for professional electrical installations. This 1-1/4 inch locknut provides a secure, vibration-resistant connection for rigid and IMC conduit systems in commercial and industrial environments. Constructed from high-quality steel with a zinc plating, it delivers excellent corrosion resistance and long-lasting durability, meeting UL 514B standards for conduit fittings. Key applications include electrical panels, junction boxes, motor control centers, and distribution equipment where reliable conduit termination is critical. The locknut's precision threading ensures a tight fit on 1-1/4 inch trade size conduit, preventing loosening from vibration or thermal cycling. Unlike standard hardware, this UL Listed fitting is specifically engineered for electrical systems, providing both mechanical strength and electrical continuity when properly installed. Ideal for electrical contractors, maintenance teams, and industrial facilities requiring code-compliant conduit connections. The zinc coating provides additional protection against moisture and chemicals in harsh environments, extending service life compared to uncoated steel fasteners. NSI Industries, a trusted manufacturer of electrical hardware since 1957, backs this product with industry-standard reliability.
