Thomas & Betts TK123A-FA EMT Set Screw Coupling

The Thomas & Betts TK123A-FA EMT Set Screw Coupling securely joins two sections of 1-inch Electrical Metallic Tubing (EMT) with a concrete-tight connection for fire alarm conduit systems. As part of the Steel City Fire Alarm fittings line from Thomas & Betts (ABB), it uses a zinc-plated steel body with a red finish to identify fire alarm circuits, and a set-screw design that delivers a robust mechanical bond when properly installed. This 1 in. trade-size coupling is designed for joining EMT conduit in commercial, industrial, and institutional environments—ideal for fire alarm, emergency communication, and security installations that require code-compliant conduit identification. Specifications include UL Listed (UL File E16592), RoHS compliant, material zinc-plated steel, finish red, construction concrete tight, installation method set screw, and packaging of 25 pieces per box (100 pieces per master carton).
