Overview

The ABB TC121A Set Screw Connector, SKU TC121A from ABB Installation Products, is a zinc-plated steel EMT connector designed for secure termination of 1/2-inch Electrical Metallic Tubing (EMT) in concrete applications. This set screw connector features a durable zinc-plated steel construction, providing robust corrosion resistance for long-term performance in harsh industrial environments. The concrete-tight design ensures stability and protection in poured concrete installations when properly taped, making it ideal for permanent embedment in concrete slabs, walls, or foundations. The connector's 1.365-inch length accommodates standard EMT conduit sizes, while the set screw mechanism delivers positive holding strength and a secure ground connection. Unlike insulated alternatives, this non-insulated version is optimized for applications where insulation is not required, reducing material costs without compromising reliability. The TC121A is part of ABB's Steel City® EMT fittings series, a trusted line of commercial-grade conduit connectors used in electrical installations across industrial, commercial, and institutional facilities. This connector is designed for compatibility with EMT conduit systems, providing a straightforward solution for electrical contractors and installers requiring dependable conduit terminations in concrete-encased environments. The zinc-plated steel construction ensures durability in sizes up to 2 inches, while the set screw design facilitates quick and secure installations with standard tools. For projects requiring concrete-tight EMT connections, the TC121A offers a cost-effective, field-proven solution that meets the demands of modern electrical installations.
