Overview
The Thomas & Betts 1-1/4 EMT connector insulated is a compression-style conduit connector engineered for reliable connections between 1-1/4 inch electrical metallic tubing (EMT) and electrical enclosures or junction boxes. Manufactured under the Steel City brand (now part of ABB), this connector delivers the durability and precision required in commercial and industrial electrical installations. The zinc-plated steel construction provides corrosion protection in dry indoor environments, while the set-screw design enables fast, tool-free installation.
Key Features
