Appleton TB150-M Unilet Terminal Block Assembly

Appleton TB150-M Unilet Type TB conduit outlet body, Form 35, delivers a robust 1-1/2 in hub conduit entry for threaded conduit systems, providing a durable access point for wiring transitions in industrial installations. Built with malleable iron, the body is triple-coated with zinc electroplate, chromate, and epoxy to resist corrosion in harsh environments, and it includes a fiber/neoprene gasket to help seal the joint against dirt and moisture. The TB150-M accommodates a 35.3 cu-in internal capacity, making it suitable for typical 1-1/2 in hub configurations and the conductors they carry, while maintaining compatibility with standard Unilet fittings. As part of Appleton’s UNILETS family, this Form 35 conduit body is designed for secure mounting and reliable service in control panels, machinery, and equipment enclosures where easy access for pulling, routing, and inspecting conductors is required. Its threaded installation and rugged metallic construction support long-term use in demanding settings without compromising protection or electrical continuity.
