Nsi Industries 240 Steel Set Screw Emt Coupling 1/2 in

Product Description

The NSI INDUSTRIES 240 is a 1/2 inch steel set screw EMT coupling designed to join two lengths of electrical metallic tubing in conduit installations. The set screw fastening method provides a secure mechanical connection without the need for threading, making field installation fast and consistent. Built from steel construction, this coupling is suited for use in standard EMT raceway systems found in commercial and residential electrical work. Licensed electricians and electrical contractors install this fitting as part of branch circuit and feeder conduit runs.

This coupling is used in 1/2 inch EMT conduit systems in both new construction and retrofit electrical installations. It is appropriate for indoor dry locations and standard raceway applications where EMT is the specified conduit type. The set screw design is common in panel feeds, junction box connections, and general branch circuit conduit work across light commercial and residential projects.

Key Features

• 1/2 inch trade size fits standard EMT conduit
• Set screw fastening for tool-accessible, secure mechanical connection
• Steel construction for durability in conduit raceway systems
• Compact coupling profile for use in tight installation spaces

Compatibility

Designed as an OEM-style replacement and standard fitting for use with 1/2 inch EMT conduit in residential and commercial electrical raceway systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 358 governing electrical metallic tubing. De-energize all circuits in the conduit run before making connections. Use an appropriate screwdriver or hex key to tighten the set screw to secure the coupling to the conduit. Ensure conduit ends are reamed and free of burrs before joining to protect wire insulation.
