Industrial ERS350CPLG Dual Rated Set Screw Coupling

The American Fittings ERS350CPLG Dual Rated Set Screw Coupling is a 3-1/2 inch conduit connector designed to join EMT, Rigid, and IMC conduits with a single set screws, providing a secure inline transition for electrical runs in commercial and industrial installations. Machined from alloy steel and finished with zinc plating and a clear chromate coating, this coupling offers corrosion resistance for exposed or damp locations while remaining compatible with standard 3-1/2 inch conduit systems used in EMT and metal conduit installations. As a dual-rated, set-screw coupling, it supports EMT-to-Rigid/IMC transitions, simplifying field work when multiple conduit types are present in a single run and reducing the need for separate connectors in mixed-conduit systems. The ERS350CPLG is part of American Fittings' family of conduit fittings, reflecting the manufacturer's long-standing focus on cross-compatibility between EMT, RMC/Rigid, and IMC conduits.
