ELCO® / Electroline® Set-Screw Type Zinc Die-Cast EMT Conduit Couplings (Sizes 1/2", 3/4", and 1")
ELCO® / Electroline® Set-Screw Type Zinc Die-Cast EMT Conduit Couplings (Sizes 1/2", 3/4", and 1")
-
The Set-Screw EMT Conduit Coupling Series (featuring ELCO® / Electroline® catalog specifications) provides concrete-tight dry-location joints between plain-end Electrical Metallic Tubing (EMT) conduits. Manufactured from high-strength zinc die-cast alloy for corrosion resistance and electrical grounding continuity. Designed with dual set screws that secure conduit ends firmly in place, preventing pull-out while maintaining internal smooth surface integrity for wire pulling. Fully compliant with NEC standards and UL Listed for safe installation across commercial, industrial, and residential electrical raceways.

Key Features & Standards
-
cULus Safety Certified: Meets rigorous UL safety standards for electrical grounding continuity and mechanical retention across listed raceway systems.
-
Zinc Die-Cast Construction: Premium metal construction offers corrosion resistance and durability without rusting.
-
Secure Dual Set-Screw Locking: Heavy-duty screws lock conduit ends firmly into position to prevent joint separation during wire pulling.
-
Smooth Internal Wire Way: Precision-molded internal stop ensures smooth transitions without snagging or damaging wire insulation.
⚠️ Safety Warning: Ensure set screws are tightened securely using the proper driver size to maintain ground continuity and mechanical integrity. Designed for dry locations and concrete-tight applications when taped; do not use in wet or rain-tight outdoor environments unless properly rated. Always adhere to National Electrical Code (NEC) guidelines during installation.
