Orbit Industries LN-150 Zinc Conduit Locknut 1-1/2 in

Product Description

The ORBIT INDUSTRIES LN-150 is a zinc die-cast conduit locknut designed to secure threaded conduits or connectors to electrical junction boxes and enclosures in wet locations. The serrated teeth on the locknut bite into the box or enclosure surface, preventing vibratory loosening of the connection over time. At 1-1/2 inch trade size, this locknut is a practical solution for electricians working with standard junction boxes that have unthreaded conduit knockout openings where a weatherproof, secure fit is required.

This locknut is suited for wet location installations where conduit terminations must remain mechanically secure. It allows standard junction boxes to be fitted with threaded conduits or connectors at unthreaded knockout openings without requiring a specialized enclosure. Typical applications include outdoor panels, wet utility enclosures, and conduit runs in areas subject to moisture exposure. Licensed electricians install this fitting as part of conduit system assembly in both residential and light commercial work.

Key Features

• Zinc die-cast construction provides corrosion resistance suitable for wet location use
• Serrated teeth grip the box or enclosure to resist vibratory loosening
• 1-1/2 inch trade size fits standard conduit and connectors of the same trade size
• Enables standard junction boxes with unthreaded knockouts to accept threaded conduit terminations
• Rated for wet location applications

Compatibility

Designed as an OEM-style replacement or new-installation locknut for 1-1/2 inch trade size threaded conduit systems terminating at electrical junction boxes or enclosures.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify power is off before working on any enclosure or junction box. Thread the locknut onto the conduit or connector and tighten firmly against the enclosure wall so the serrated teeth seat fully into the metal surface. Do not overtighten to the point of cracking the die-cast body.
