Technical Specifications

This 3-inch trade size conduit hub features malleable iron construction with precision-machined threads for secure conduit connections. The hub measures 4.44" width x 3.15" height x 5.05" depth, providing robust connection capability while maintaining compact installation footprint. The malleable iron material offers superior strength-to-weight ratio compared to steel alternatives, with enhanced corrosion resistance for long-term performance. NEC/CEC compliant design ensures proper grounding continuity and code compliance in commercial and industrial installations.

Installation Process

1. Verify masonry box opening size matches 3" trade size requirements
2. Clean threads on both conduit hub and connecting conduit to ensure proper engagement
3. Apply appropriate thread sealant if required for environmental sealing
4. Thread conduit hub into masonry box opening, ensuring full thread engagement
5. Tighten to manufacturer specifications using appropriate wrenching surfaces
6. Verify grounding continuity through the connection system
7. Complete conduit installation per NEC/CEC requirements for proper support spacing

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial installations
• Municipal Infrastructure - Government buildings, schools, and public utility installations
• Heavy-Duty Electrical Panels - Main distribution panels and electrical equipment connections
• Masonry Construction - Concrete and block wall electrical system integration
• Equipment Connections - Motor control centers, switchgear, and industrial equipment feeds
• Outdoor Installations - Weather-exposed applications requiring corrosion resistance
• High-Vibration Environments - Industrial settings where mechanical stress resistance is critical

Masonry Box Connection Benefits

Masonry boxes with conduit hubs provide superior structural integration compared to standard outlet boxes, offering enhanced support for heavy conduit runs and equipment connections. The rigid mounting in concrete or masonry walls eliminates movement and stress on electrical connections, while the robust construction handles the mechanical demands of large conduit systems and heavy cable pulls.

Why Choose Malleable Iron Construction?

Malleable iron offers the perfect combination of strength, durability, and workability for demanding electrical applications. Unlike brittle cast iron or lighter steel alternatives, malleable iron provides exceptional impact resistance while maintaining precise dimensional tolerances. This Crouse-Hinds MHUB hub leverages over 100 years of electrical manufacturing expertise to deliver the reliability and performance that electrical professionals demand in critical installations.
