Technical Specifications

This 1-1/4" trade size EMT coupling features zinc plated steel construction with four set screws for maximum holding power. The coupling measures 2.75" in length, 1.75" in width and height, weighing 0.42 pounds. Designed specifically for EMT conduit systems, it provides reliable connections in ordinary/non-hazardous locations while maintaining NEC/CEC compliance standards. The precision-engineered design ensures proper fit with standard 1-1/4" EMT conduit for professional electrical installations.

Installation Process

1. Verify EMT conduit ends are cut square and deburred for proper insertion
2. Insert first conduit section fully into one end of the coupling
3. Tighten the two set screws on that end to secure the conduit firmly
4. Insert second conduit section into the opposite end of the coupling
5. Tighten remaining two set screws to complete the connection
6. Verify both conduit sections are fully seated and securely fastened

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail stores, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and warehouse installations
• Conduit Extensions - Joining EMT conduit runs in long electrical distribution systems
• Equipment Connections - Connecting conduit to electrical panels, motor control centers, and switchgear
• Renovation Projects - Extending existing EMT conduit systems during facility upgrades
• Municipal Infrastructure - Schools, government buildings, and public facility electrical systems
• Data Centers - Power distribution conduit systems requiring reliable connections
• Healthcare Facilities - Critical power systems where connection reliability is essential

EMT Coupling System Benefits

EMT couplings provide the most reliable method for joining electrical metallic tubing in professional installations. Unlike compression fittings that rely on deformation, set screw couplings maintain the conduit's structural integrity while providing superior holding power. The four-screw design distributes gripping force evenly, preventing conduit damage while ensuring connections that won't loosen over time due to thermal cycling or mechanical stress.

Why Choose Zinc Plated Steel Construction?

Zinc plated steel offers the ideal combination of strength, durability, and corrosion resistance for EMT coupling applications. The zinc coating provides excellent protection against moisture and environmental corrosion, while the steel base material delivers the mechanical strength needed for secure conduit connections. This material combination ensures decades of reliable service in commercial and industrial electrical systems, making it the preferred choice of electrical contractors nationwide.
