Overview

The NSi Industries 3/4" Malleable Iron Rigid Set Screw Connector (SKU: 3501) is a durable, threadless conduit fitting designed for rigid and intermediate metal conduit systems. Constructed from high-strength malleable iron, this connector eliminates the need for conduit threading, reducing installation time and labor costs. The hardened steel set screw provides a positive mechanical grip and ensures ground continuity, capable of carrying ground fault currents up to 20,000 amps RMS. The nylon insulated throat prevents insulation damage, reduces wire pulling effort by up to 50%, and meets UL 514B, CSA C22.2 No. 18, and NFPA 70-1999 standards. Finished with electro zinc plating and chromate coating, it resists corrosion and wear in demanding environments. Ideal for plumbing, HVAC, electrical installations, and industrial piping, this connector is UL listed (File No: E-23018) and CSA certified (LR-2884). Made in the USA, it delivers reliable performance in concrete-tight applications and is compatible with standard 3/4" conduit systems.
