Orbit Industries SLN-350 Steel Conduit Locknut 3-1/2 in

Product Description

The ORBIT INDUSTRIES SLN-350 is a steel conduit locknut designed to secure threaded conduits or connectors to electrical junction boxes and enclosures. Sized for 3-1/2 inch trade size conduit, it allows standard junction boxes to be used at unthreaded conduit knockout openings in wet and damp locations. Serrated teeth on the locknut bite into the box or enclosure surface to resist vibratory loosening over time. A zinc electroplating finish provides corrosion protection in damp environments. Licensed electricians and conduit installers use this hardware as a standard part of conduit termination work.

The SLN-350 is suited for use in both wet and damp location installations where conduit must be anchored securely to a junction box or electrical enclosure. It works with standard unthreaded knockout openings and is appropriate for commercial and residential electrical conduit systems requiring reliable mechanical connection and corrosion-resistant hardware at 3-1/2 inch trade size.

Key Features

• 3-1/2 inch trade size fits standard knockout openings of the same dimension
• Serrated teeth grip the box or enclosure surface to prevent loosening from vibration
• Zinc electroplated steel construction provides corrosion resistance in damp locations
• Rated for use in wet and damp location applications
• Enables use of standard junction boxes with unthreaded conduit knockouts

Compatibility

Designed as an OEM-style replacement or standard-service locknut for electrical junction boxes and enclosures with 3-1/2 inch trade size conduit knockout openings.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for conduit terminations. De-energize all circuits in the junction box or enclosure before beginning work. Thread the locknut onto the conduit or connector and tighten against the enclosure wall so the serrated teeth seat firmly into the surface. Do not overtighten to the point of distorting the enclosure wall or stripping the conduit threads.
