Overview

NSI Industries 241-SBLK EMT Coupling is a 3/4" steel coupling designed for rigid electrical metallic tubing (EMT) installations. Constructed from durable steel, this coupling provides a secure mechanical joint between EMT conduits, ensuring electrical continuity and grounding compliance per NEC standards. The black color-coding allows for quick visual identification from either inside or outside the junction box, reducing inspection time and errors during installation or maintenance. Compatible with standard EMT conduit sizes, this coupling features a threaded design for easy assembly with hand tools or power drivers. Ideal for commercial, industrial, and residential electrical systems where reliable conduit connections are critical. The steel construction resists corrosion and mechanical stress, maintaining long-term performance in exposed or concealed applications. NSI Industries, a trusted manufacturer in electrical infrastructure, ensures this coupling meets industry specifications for durability and electrical safety.
  • 3/4" EMT conduit size compatibility
