Technical Specifications

This 3/4" trade size conduit hub features malleable iron construction with precision-machined threads for secure conduit connections. The hub measures 1.84" in length, 1.62" in width, and 1.51" in height, with a compact 0.25 lb weight that won't add unnecessary bulk to installations. The malleable iron material provides superior strength compared to steel alternatives while maintaining excellent workability for field modifications when necessary. All dimensions and threading comply with NEC/CEC standards for masonry box applications.

Installation Process

1. Verify masonry box opening size matches 3/4" trade size requirements
2. Thread conduit hub into masonry box opening, ensuring proper thread engagement
3. Tighten hub securely using appropriate tools, avoiding over-torquing that could damage threads
4. Insert conduit into hub opening, ensuring proper insertion depth
5. Secure conduit connection according to conduit type requirements (set screw, compression, etc.)
6. Verify mechanical integrity and proper grounding continuity throughout connection

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, and mixed-use developments
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial installations
• Institutional Projects - Schools, hospitals, government buildings, and municipal facilities
• Masonry Construction - Concrete block, brick, and poured concrete electrical installations
• Outdoor Installations - Weather-exposed locations requiring robust mechanical connections
• Equipment Connections - Motor control centers, switchgear, and distribution panel connections
• Underground Applications - Concrete-encased conduit systems and vault installations
• Heavy-Duty Environments - High-vibration areas and mechanically demanding installations

Masonry Box Connection Benefits

Conduit hubs provide essential mechanical protection and code-compliant connections between conduit systems and masonry boxes. Unlike field-improvised connections, the MHUB series ensures proper thread engagement, maintains grounding continuity, and provides the mechanical strength required for long-term reliability. The precision-engineered design eliminates common installation problems while ensuring compliance with electrical codes.

Why Choose Malleable Iron Construction?

Malleable iron offers the perfect combination of strength, workability, and longevity for demanding electrical installations. Unlike brittle cast iron or softer steel alternatives, malleable iron provides superior impact resistance while maintaining the ability to be field-modified when necessary. This Eaton Crouse-Hinds hub represents over 100 years of electrical fitting innovation, delivering the professional-grade performance that electrical contractors depend on for critical installations.
