Overview

The NSi Industries 233-US is a 1-1/4" steel set screw connector engineered for secure EMT conduit attachment to electrical enclosures, junction boxes, or panels. Constructed from high-strength steel with a zinc electro-plated finish, this connector delivers corrosion resistance and durability in harsh environments, including outdoor installations, wet locations, and areas exposed to chemicals or moisture. Designed for steel EMT conduit, the 233-US features an insulated throat to prevent electrical shorts and is concrete-tight when taped, providing a secure seal against concrete infiltration. The set screw design ensures a tight, tamper-resistant fit, while the zinc plating enhances longevity in corrosive conditions. Key specifications include a trade size of 1-1/4", dimensions of A=2.750", B=2.000", and C=0.500", and a temperature rating of 105°C. Ideal for machinery, equipment assembly, structural frameworks, and other applications requiring a vibration-resistant, reliable connection, the 233-US is a trusted solution for securing EMT conduit in demanding industrial environments.
