Overview

The ABB TL 291 Capped Corner Coupling (SKU: TL 291) is a die-cast zinc coupling designed for secure 1/2-inch conduit connections in industrial and commercial electrical installations. This coupling features a 1.00-inch opening and measures 1.81 inches in length, providing a precise fit for threadless rigid metal conduit and intermediate metal conduit systems. The capped corner design simplifies installation by reducing the need for additional fittings, saving labor time and costs. Constructed from durable die-cast zinc, the TL 291 offers excellent corrosion resistance and mechanical strength, ensuring long-term reliability in demanding environments. It is suitable for concrete-tight applications and capable of carrying ground fault currents up to 10,000 amps RMS (for 1/2" through 1 1/2" sizes). The coupling includes a case-hardened ring that bites into the conduit for high-quality continuity and grip, while a nylon insulator protects conductors and reduces wire-pulling effort by up to 50%. Certified by U.L. (File No: E-23018) and CSA (LR-2884), the TL 291 meets rigorous industry standards for electrical safety and performance. Ideal for electrical contractors, maintenance professionals, and industrial equipment installers, this coupling ensures robust, code-compliant conduit connections in commercial buildings, manufacturing facilities, and infrastructure projects.
