Orbit Industries SLN-600 Steel Conduit Locknut 6 Inch

Product Description

The ORBIT INDUSTRIES SLN-600 is a steel conduit locknut designed to secure threaded conduits or connectors to electrical junction boxes and enclosures. Built for 6-inch trade size applications, it features serrated teeth that bite into the box or enclosure wall to resist vibratory loosening over time. A zinc electroplated finish provides corrosion protection, making this locknut suitable for use in both damp and wet locations. Licensed electricians and conduit installers rely on this hardware to create secure, code-appropriate terminations in commercial and industrial wiring systems.

The SLN-600 is used in applications where threaded conduits or connectors must be fastened to junction boxes or enclosures with unthreaded knockout openings. Its wet-location rating makes it appropriate for outdoor, underground, or otherwise moisture-exposed conduit runs. The 6-inch trade size suits large conduit installations commonly found in commercial, industrial, and utility electrical systems. This locknut allows standard junction boxes to be used in applications that would otherwise require specialized fittings.

Key Features

• Serrated teeth bite into box and enclosure surfaces to resist vibratory loosening
• Zinc electroplated steel construction for corrosion resistance in damp and wet locations
• Rated for wet location use, allowing standard junction boxes to pair with unthreaded conduit knockouts
• 6-inch trade size for large conduit termination applications
• UL listed under File Number E310658

Compatibility

Designed as an OEM-style replacement or new-install hardware for 6-inch trade size threaded conduit and connector terminations at standard electrical junction boxes and enclosures in wet or damp locations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits before working on any junction box or enclosure. Thread the locknut onto the conduit or connector and tighten securely so the serrated teeth seat firmly against the box wall. Avoid over-tightening, which may distort the knockout opening or damage the enclosure.
