Nsi Industries 246 Set Screw Coupling 2.5 Inch

Product Description

The NSI INDUSTRIES 246 is a 2.5-inch set screw coupling designed to join two sections of electrical metallic tubing (EMT) in conduit installations. The set screw fastening method provides a secure, tool-tightened mechanical connection without threading, making it a practical choice for straight-run conduit runs in commercial and residential electrical work. Licensed electricians and electrical contractors install this fitting as a standard component in conduit raceway systems where a reliable EMT-to-EMT joint is required.

This coupling is suited for 2.5-inch EMT conduit systems used in commercial buildings, industrial facilities, and residential service installations. It is appropriate for indoor and dry-location applications where EMT is the specified raceway. The set screw design allows for straightforward field installation during new construction or conduit retrofit projects.

Key Features

• Accepts 2.5-inch EMT conduit for straight coupling connections
• Set screw fastening method for a secure mechanical grip without threading
• Compact coupling profile suited for standard raceway layouts
• Designed for use by licensed electricians in code-compliant installations

Compatibility

Designed as an OEM-style replacement and standard fitting for 2.5-inch EMT conduit systems in residential and commercial electrical raceway applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the work area before beginning conduit work. A set screw driver or hex key is required to tighten the securing screws to a firm mechanical connection. Do not over-tighten the set screws, as this may deform the conduit wall or strip the screw threads.
