Overview

The NSI Industries 246-DC is a zinc die cast set screw coupling engineered for 2.5" EMT conduit systems. Unlike malleable iron or aluminum alternatives, this coupling leverages corrosion-resistant zinc die cast construction while meeting UL 514B standards 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 4" in length (Dimension A) and 3.26" in width (Dimension B), this coupling is ideal for industrial, commercial, and utility electrical installations where reliable conduit connections are critical. The ball burnished, mirror-smooth finish provides long-term durability in both indoor and outdoor environments, resisting rust and maintaining electrical continuity. Suitable for joining two lengths of EMT conduit from 1/2" through 1 1/4" trade sizes, this coupling delivers concrete-tight performance when taped for sizes 1.5" through 4". Contractors and maintenance teams choose this coupling for its balance of strength, corrosion resistance, and installation efficiency in EMT conduit systems.
