Technical Specifications

This 1-1/4" trade size coupling is constructed from premium malleable iron and designed specifically for rigid and IMC conduit applications. The coupling measures 2.75" in length with a 2.19" width and height, weighing 0.7 pounds for substantial mechanical protection. The set screw connection method provides secure attachment while maintaining excellent grounding continuity. Compliant with NEC/CEC standards, this coupling is rated for ordinary/non-hazardous locations and delivers the professional-grade performance expected from Eaton Crouse-Hinds electrical fittings.

Installation Process

1. Verify conduit ends are cut square and deburred to ensure proper fit and prevent wire damage
2. Insert first conduit section fully into one end of the coupling until it reaches the internal stop
3. Insert second conduit section into the opposite end, ensuring both conduits are properly seated
4. Tighten set screws securely using appropriate tools to achieve proper mechanical and electrical connection
5. Verify coupling is properly aligned and conduits are firmly secured before proceeding with installation
6. Test grounding continuity if required by local electrical codes or installation specifications

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial installations
• Equipment Connections - Motor control centers, switchgear, and electrical distribution panels
• Conduit Extensions - Joining conduit runs in renovation and expansion projects
• Municipal Infrastructure - Government buildings, public facilities, and utility installations
• Heavy-Duty Applications - Installations requiring maximum mechanical protection and durability
• Grounding Systems - Applications where continuous grounding path is critical for safety
• Long-Term Installations - Projects requiring decades of reliable service without maintenance

Set Screw Coupling System Benefits

Set screw couplings offer significant advantages over threaded alternatives in many applications. They eliminate the need for precise threading, reduce installation time, and provide excellent mechanical strength. The set screw design allows for easier alignment of conduit runs and provides a secure connection that won't loosen over time. This makes them ideal for applications where conduit positioning is critical or where frequent modifications may be required.

Why Choose Malleable Iron Construction?

Malleable iron provides superior strength and durability compared to standard steel fittings, making it the preferred choice for demanding electrical installations. This advanced material offers excellent impact resistance, superior threading characteristics, and enhanced corrosion resistance. The malleable iron construction ensures this coupling will maintain its mechanical and electrical integrity throughout decades of service, even in challenging industrial environments where vibration, thermal cycling, and mechanical stress are common.
