This heavy-duty locknut delivers exceptional holding power and long-term reliability for professional electrical contractors working with 3" rigid steel and IMC conduit systems.

Key Features & Benefits

Superior Material Construction

• Malleable Iron Construction - Provides superior strength compared to standard steel locknuts, resisting cracking and deformation under high torque applications
• Corrosion Resistant Finish - Engineered coating protects against rust and environmental degradation for decades of reliable service
• Precision Threading - Machine-cut threads ensure smooth installation and optimal grip on conduit systems
• Heavy-Duty Design - Robust construction handles the demanding requirements of large 3" conduit installations

Professional Installation Advantages

• Secure Conduit Termination - Creates reliable mechanical connection between conduit and electrical enclosures
• Easy Installation - Standard locknut design allows quick installation with common electrical tools
• Versatile Compatibility - Works with both rigid steel conduit and intermediate metal conduit (IMC) systems
• Code Compliant Design - Meets NEC/CEC requirements for conduit termination in ordinary locations

Technical Specifications

This 3" trade size locknut features malleable iron construction with precision-machined threads compatible with rigid steel and IMC conduit systems. The locknut measures 3.69" in length, 2.43" in width, and 1.37" in height, weighing 0.15 pounds for easy handling during installation. Designed for ordinary/non-hazardous locations with NEC/CEC compliance, this fitting provides reliable conduit termination in commercial and industrial electrical applications.

Installation Process

1. Thread conduit through knockout opening in electrical enclosure or panel
2. Position conduit end flush with interior surface of enclosure wall
3. Thread locknut onto conduit from inside the enclosure
4. Tighten locknut using appropriate locknut wrench or spanner tool
5. Ensure locknut is firmly seated against enclosure wall for secure connection
6. Verify conduit is properly grounded through locknut connection

Applications

Perfect for:

• Commercial Buildings - Office complexes, retail centers, hospitals, and educational facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and heavy industrial installations
• Electrical Panel Connections - Main distribution panels, sub-panels, and motor control centers
• Equipment Terminations - Switchgear, transformers, and large electrical equipment connections
• Municipal Infrastructure - Government buildings, schools, and public facility electrical systems
• Heavy-Duty Conduit Runs - Large feeder circuits and high-capacity electrical distribution
• Outdoor Installations - Weather-resistant applications requiring durable conduit termination
• Maintenance and Retrofit - Replacement of worn locknuts in existing electrical systems

Rigid/IMC Conduit System Benefits

Rigid steel and IMC conduit systems provide superior mechanical protection for electrical conductors compared to flexible conduit options. The robust construction offers excellent crush resistance, impact protection, and electromagnetic shielding. These systems are ideal for exposed installations, underground applications, and areas requiring maximum conductor protection. Proper locknut termination ensures system integrity and maintains grounding continuity throughout the installation.

Why Choose Malleable Iron Construction?

Malleable iron offers significant advantages over standard steel in locknut applications. The material's superior ductility prevents cracking under high installation torque, while its enhanced strength provides long-term holding power that won't loosen over time. This Eaton Crouse-Hinds locknut represents over 100 years of electrical fitting innovation, delivering the reliability and performance that electrical professionals demand for critical 3" conduit installations.
