Orbit Industries LN-300 Zinc Conduit Locknut 3 Inch

Product Description

The ORBIT INDUSTRIES LN-300 is a zinc die-cast conduit locknut designed to secure threaded conduits or connectors to electrical junction boxes and enclosures. It is rated for use in wet locations, making it suitable for outdoor and damp-environment electrical installations. The serrated teeth on the locknut bite into the box or enclosure surface to resist vibratory loosening over time. This 3-inch trade size locknut is installed by licensed electricians during conduit runs where a mechanical and electrical bond between conduit and enclosure is required.

The LN-300 is used in residential and commercial electrical installations where threaded conduit or connectors must be fastened to junction boxes or enclosures with unthreaded knockout openings. Its wet-location rating makes it appropriate for exterior panels, weatherproof enclosures, and other installations subject to moisture exposure. The 3-inch trade size fits standard 3-inch conduit knockout openings.

Key Features

• Zinc die-cast construction for corrosion resistance in wet locations
• Serrated teeth grip box and enclosure surfaces to prevent vibratory loosening
• Rated for wet location use, suitable for outdoor and damp installations
• Allows standard junction boxes to be used with unthreaded conduit knockouts
• 3-inch trade size for compatibility with standard 3-inch conduit systems

Compatibility

Designed as an OEM-style replacement or standard-use locknut for 3-inch trade size threaded conduit and connector installations at electrical junction boxes and enclosures in wet or dry locations.

Installation Notes

Installation is performed by a licensed electrician. De-energize the circuit and verify lockout/tagout procedures before working on any enclosure or junction box. The locknut is threaded onto the conduit or connector and tightened against the box wall so the serrated teeth engage the metal surface firmly. Follow applicable NEC requirements for conduit connections in wet locations.
