Nsi Industries 241 Steel Set Screw Emt Coupling 3/4 Inch

Product Description

The NSI INDUSTRIES 241 is a 3/4 inch steel set screw coupling designed for joining sections of electrical metallic tubing (EMT) conduit. It creates a secure, rigid mechanical connection between two conduit runs using a set screw fastening method, eliminating the need for compression tools. This fitting is a standard component in commercial and residential electrical raceway systems and is installed by licensed electricians during rough-in and finish wiring work.

This coupling is suited for use in dry or damp locations where EMT conduit is the raceway of choice. It fits standard 3/4 inch EMT conduit and is commonly used in panel feeders, branch circuit runs, and equipment connections in both new construction and retrofit electrical work. The steel construction provides durability in typical indoor conduit applications.

Key Features

• Set screw fastening design for quick, tool-simple installation without compression fittings
• Steel construction for mechanical strength in raceway assemblies
• Sized for 3/4 inch EMT conduit — a common trade size in commercial and residential wiring
• Provides a continuous, rigid mechanical connection between conduit sections

Compatibility

Designed as an OEM-style replacement fitting for standard 3/4 inch EMT conduit systems in residential and commercial electrical installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 358 governing EMT conduit systems. De-energize all circuits in the affected raceway before working on conduit connections. Insert each conduit end fully into the coupling body and tighten the set screw securely to ensure a reliable mechanical and bonding connection. Do not use this coupling on rigid metal conduit (RMC) or intermediate metal conduit (IMC) — it is rated for EMT only.
