Overview

The NSI Industries 246-DC is a zinc die cast set screw coupling designed for 2 1/2 inch EMT conduit systems. Unlike malleable iron or aluminum alternatives, this coupling leverages zinc die cast construction to deliver corrosion resistance while maintaining UL compliance equivalent to steel fittings. The set screw design ensures a secure mechanical connection without requiring additional tools beyond a standard screwdriver, enabling faster installations compared to three-piece designs. Measuring 2 1/2 inches in size, this coupling is ideal for industrial, commercial, and utility electrical installations where reliable conduit connections are critical. The zinc die cast material provides long-term durability in both indoor and outdoor environments, resisting rust and maintaining electrical continuity. NSI Industries specifies this fitting meets the same stringent UL tests as steel components, offering error-free performance in demanding applications. Contractors and maintenance teams choose this coupling for its balance of strength, corrosion resistance, and installation efficiency in EMT conduit systems.
