Eaton Crouse-Hinds UNL105 SA Union - Hazardous Locations

Copper-free aluminum construction reduces weight and improves corrosion resistance, delivering a safer, easier-to-handle union for demanding installations. The UNL105 SA's material choice translates into lower transport costs on busy work sites and easier field servicing without sacrificing strength. In hazardous locations, lighter components also minimize worker fatigue during long-term maintenance and upgrades. Conduit compatibility is another core benefit. Designed for rigid/IMC conduit and a 1/2 inch - 1/2 inch trade size, it locks into standard fittings without special adapters. This streamlines procurement and inventory management across projects, while ensuring dependable electrical continuity in both new builds and retrofit work. Compliance and certifications provide business value. NEC/CEC standards, hazard ratings for Class I, II, and III locations, and UL/CSA listings give procurement teams confidence to pass approvals. By aligning with these requirements, projects avoid costly rework and delay. Installation efficiency is a practical advantage. The compact dimensions (2.69 in length, 2 in height, 1.53 in width) fit tight panels and crowded enclosures, reducing panel depth and easing routing. Field technicians benefit from straightforward assembly, fewer fasteners, and predictable, repeatable joints in explosion-protected systems. Long-term value comes from reliability and reuse. The UNL105 SA is part of Eaton Crouse-Hinds' UNL family, ensuring consistent performance across batch productions and service life. For engineers, that means consistent conduit unions that simplify maintenance planning, spare-part stocking, and total cost of ownership in hazardous-location applications.
