• Grounding Continuity - Non-insulated design maintains equipment grounding path integrity
• Professional Standards - Manufactured to strict quality standards for reliable long-term performance

Technical Specifications

This connector features a 3/4" trade size designed specifically for flexible metal conduit (FMC) applications. The zinc die cast construction provides dimensional stability measuring 6.22" in length, 2.45" in width, and 1.94" in height, with a lightweight 0.09 lb design that won't add unnecessary weight to electrical installations. The straight, non-insulated configuration ensures proper grounding continuity while meeting NEC/CEC compliance standards for ordinary/non-hazardous locations.

Installation Process

1. Select appropriate knockout size in electrical enclosure or junction box for 3/4" connector
2. Insert connector through knockout from inside of enclosure, ensuring proper orientation
3. Thread locknut onto connector from outside of enclosure and tighten securely
4. Prepare flexible metal conduit end by ensuring clean, square cut without burrs
5. Insert FMC into connector opening and rotate clockwise to engage internal gripping mechanism
6. Verify secure mechanical connection by gently tugging on installed conduit

Applications

Perfect for:

• Motor Control Centers - Flexible connections to variable frequency drives and motor starters
• Panel Board Connections - FMC terminations in electrical distribution panels and load centers
• Equipment Wiring - Flexible conduit connections to transformers, switchgear, and control equipment
• Commercial Buildings - Office complexes, retail facilities, and institutional electrical systems
• Industrial Facilities - Manufacturing plants, processing facilities, and warehouse electrical installations
• Machinery Connections - Equipment requiring flexible conduit for vibration isolation
• Control Panel Wiring - Connections between control enclosures and field devices
• Retrofit Projects - Upgrading existing electrical systems with reliable FMC connections

Flexible Metal Conduit System Benefits

Flexible metal conduit systems offer superior protection for electrical conductors while providing the flexibility needed for equipment connections subject to vibration or movement. Unlike rigid conduit systems, FMC allows for thermal expansion and contraction while maintaining excellent mechanical protection. The screw-in connector design provides a more secure connection than standard compression fittings, ensuring long-term reliability in demanding applications.

Why Choose Zinc Die Cast Construction?

Zinc die cast construction offers exceptional dimensional accuracy and consistency compared to other manufacturing methods. The precision casting process ensures perfect thread engagement and reliable sealing performance, while the inherent corrosion resistance of zinc provides long-term durability in challenging electrical environments. This material choice, combined with Eaton Crouse-Hinds' century of electrical innovation, delivers the professional-grade performance that electrical contractors depend on for critical installations.
