Technical Specifications
This 4" trade size thin construction locknut features steel construction with precise threading for rigid and IMC conduit systems. The compact design measures 3.87" in length, 2.48" in width, and only 1.3" in height, making it ideal for installations where space is at a premium. The lightweight 0.22 lb construction reduces overall system weight while maintaining the strength required for secure conduit termination in commercial and industrial applications.
Installation Process
- Verify conduit end is properly reamed and deburred to prevent wire damage
- Thread conduit through enclosure knockout or hub opening
- Position conduit at desired depth within enclosure
- Thread thin construction locknut onto conduit from inside enclosure
- Tighten locknut securely using appropriate locknut wrench or spanner tool
- Verify conduit is properly secured and grounding continuity is maintained
Applications
Perfect for:
- Shallow Electrical Panels - Switchboards and panelboards with limited internal clearance
- Equipment Connections - Motor control centers, variable frequency drives, and control panels
- Industrial Machinery - Manufacturing equipment with space-constrained electrical connections
- Commercial Buildings - Office complexes, retail facilities, and institutional installations
- Retrofit Projects - Upgrading existing systems where space modifications are limited
- High-Density Installations - Multiple conduit entries in compact enclosures
- HVAC Systems - Air handling units and rooftop equipment with tight clearances
- Data Centers - Server rooms and telecommunications facilities requiring precise fit
Thin Construction Locknut Advantages
Thin construction locknuts provide critical space savings in modern electrical installations where equipment density continues to increase. Unlike standard locknuts, the reduced profile allows for proper conduit termination in shallow enclosures, equipment with limited internal clearance, and installations where multiple conduits must enter close proximity. This design innovation enables compliance with NEC spacing requirements while maximizing usable enclosure space.
Why Choose Steel Construction?
Steel construction provides the optimal balance of strength, durability, and cost-effectiveness for rigid and IMC conduit systems. The material offers superior thread engagement compared to lighter alternatives, ensuring secure long-term connections that maintain grounding continuity. Steel's proven performance in industrial environments, combined with Eaton Crouse-Hinds' precision manufacturing, delivers the reliability electrical contractors have trusted for over 100 years.
