Thomas Betts TC227SC Emt Conduit Connector 2.5 in Set Screw

Product Description

The THOMAS BETTS TC227SC is a straight, set screw conduit connector designed for use with electrical metallic tubing (EMT). Built from die cast zinc, this connector provides a concrete-tight fitting where EMT enters an enclosure, junction box, or panel. The 2-1/2 inch trade size accommodates larger EMT runs common in commercial and industrial wiring installations. The set screw connection method allows secure attachment without threading, making termination straightforward. This connector is non-insulated and intended for standard conduit-to-box applications handled by licensed electricians.

This connector is used in residential, commercial, and light industrial electrical installations where EMT conduit must be terminated at an enclosure or panel knockout. The concrete-tight rating makes it suitable for installations where moisture and dust resistance are required at the conduit entry point. Typical applications include service entries, panel terminations, and conduit runs through concrete or masonry walls. The straight connector profile simplifies alignment when conduit approaches a box or enclosure directly.

Key Features

• Set screw connection for secure, tool-based conduit termination without threading
• Die cast zinc construction provides durability and corrosion resistance in standard environments
• Concrete-tight rating suitable for damp or dusty installation areas

Compatibility

Designed as an OEM-style replacement and standard fitting for 2-1/2 inch trade size EMT conduit systems in commercial and residential electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the affected panel or enclosure before beginning conduit termination work. Tighten the set screw firmly using an appropriate screwdriver or hex key to ensure a secure, concrete-tight connection. Verify that the knockout size on the enclosure matches the 2-1/2 inch trade size before installation.
