Technical Specifications

This connector features a 3-1/2" trade size designed specifically for flexible metal conduit (FMC) applications. The zinc die cast construction provides exceptional strength-to-weight ratio while maintaining precise dimensional tolerances. The straight, non-insulated design ensures proper grounding continuity throughout the electrical system. Product dimensions are 7.6" height × 5.8" width × 5.7" depth with a weight of 1.44 pounds, making it suitable for heavy-duty applications while remaining manageable for installation. The squeeze-type connection mechanism provides secure conduit retention without requiring additional hardware.

Installation Process

1. Verify conduit end is cut square and deburred to prevent damage to internal conductors
2. Insert flexible metal conduit fully into the connector body until it seats against the internal stop
3. Position the squeeze mechanism over the conduit insertion point
4. Apply compression force to secure the conduit within the connector body
5. Thread connector into electrical enclosure or junction box to specified torque
6. Verify secure mechanical connection and proper grounding continuity

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial applications
• Distribution Panels - Main electrical panels, sub-panels, and load centers requiring large conduit connections
• Motor Control Centers - Equipment connections where flexible conduit provides vibration isolation
• Switchgear Applications - High-capacity electrical distribution systems
• Equipment Connections - HVAC units, pumps, and other mechanical equipment requiring flexible connections
• Renovation Projects - Retrofit installations where flexible routing is advantageous
• Municipal Infrastructure - Schools, government buildings, and public facilities

Flexible Metal Conduit System Benefits

Flexible metal conduit systems excel in applications requiring vibration isolation, thermal expansion accommodation, or complex routing around obstacles. The 3-1/2" trade size accommodates substantial conductor loads while maintaining the flexibility advantages that rigid conduit cannot provide. This makes FMC ideal for equipment connections, retrofit installations, and applications where conduit routing must navigate around existing structural elements or mechanical systems.

Why Choose Zinc Die Cast Construction?

Zinc die casting provides superior dimensional accuracy and consistency compared to other manufacturing methods. This precision ensures reliable thread engagement, proper fit with electrical enclosures, and long-term mechanical integrity. The inherent corrosion resistance of zinc construction extends service life in challenging environments, while the material's strength characteristics provide excellent resistance to mechanical stress and vibration. For electrical professionals who demand reliable performance in critical applications, zinc die cast connectors represent the premium choice for flexible metal conduit terminations.
