Southwire LNS150 Sealing Locknut Steel 1-1/2 Inches 10 Pack

Product Description

The SOUTHWIRE LNS150 is a 1-1/2 inch rigid sealing locknut made from zinc electroplated steel, designed to secure threaded conduit or conduit connectors to electrical junction boxes and enclosures in wet or damp locations. A built-in gasket compresses against the box surface to form a watertight seal, allowing standard junction boxes with unthreaded knockout openings to be used in raintight applications. This 10-pack is a common stocking item for licensed electricians working on outdoor panels, service entrances, wet utility installations, and similar conduit work.

These sealing locknuts are suited for residential and commercial electrical installations where conduit enters a box or enclosure exposed to moisture. They work with 1-1/2 inch threaded rigid metal conduit and compatible threaded connectors. The gasketed design eliminates the need for separate sealing fittings when terminating conduit at standard boxes in wet locations, streamlining installation in outdoor, underground, and other damp-environment conduit runs.

Key Features

• 1-1/2 inch trade size fits standard 1-1/2 inch threaded conduit and connectors
• Gasketed sealing surface creates a watertight, raintight seal at the box knockout
• Zinc electroplated steel construction provides corrosion resistance in damp environments
• Allows standard junction boxes to serve wet-location conduit terminations without additional fittings
• Sold in a 10-pack for efficient stocking and multi-point installations

Compatibility

Designed as an OEM-style replacement and direct equivalent to Madison Electric LNS-150, Madison LNS-150, and Topaz 285. Fits 1-1/2 inch threaded rigid conduit knockouts on standard electrical junction boxes and enclosures.

Installation Notes

Installation is performed by licensed electricians in accordance with applicable NEC requirements for wet and damp location conduit terminations. De-energize the circuit and verify the box or enclosure is free of voltage before beginning work. Thread the locknut onto the conduit or connector and tighten until the gasket seats firmly and evenly against the box surface to ensure a watertight seal. Do not overtighten to the point of damaging the gasket, as this will compromise the raintight performance.
