Overview

The ABB 680-TB 2 Inch Coupling is a heavy-duty, threadless metal conduit coupling designed for reliable electrical installations. Engineered for Rigid Metal Conduit (RMC) and Intermediate Metal Conduit (IMC), this coupling eliminates the need for threading conduit ends, reducing installation time and labor costs. Constructed from thick-wall steel with a hardened hex head cup point screw, the 680-TB ensures a secure, vibration-resistant connection while maintaining ground continuity up to 20,000 amps RMS. The coupling features a positive center stop for precise alignment and a nylon insulated throat to prevent insulation damage and reduce installation effort. Certified concrete-tight, this coupling meets UL and CSA standards (File No. E-23018, CSA 2884) for use in demanding industrial and commercial environments. Ideal for electrical contractors and maintenance professionals, the 680-TB delivers durable, code-compliant conduit connections in applications requiring robust mechanical and electrical performance.
