Steel City TK122A 3/4 in EMT Set-Screw Coupling joins two sections of EMT conduit with a compact, secure connection. The steel body is zinc-plated for corrosion resistance, and the fitting is designed for 3/4 in EMT conduit, with an overall length of about 1-7/8 in. It uses set screws to clamp the conduits, delivering a rigid joint that maintains alignment in wall or ceiling runs in commercial electrical installations. As a standard EMT fitting in the Steel City/Thomas & Betts family, TK122A is widely stocked by electrical distributors for reliable, code-compliant conduit connections.
