Southwire LNS200I Sealing Locknut Steel 2 Inches

Product Description

The SOUTHWIRE LNS200I is a 2-inch steel sealing locknut designed to secure conduit fittings to enclosures, panels, and junction boxes while providing a weathertight or moisture-resistant seal at the entry point. Manufactured from steel for durability in demanding environments, this locknut is a standard component in conduit installation work across both commercial and industrial electrical systems. Electricians and electrical contractors install this fitting as part of a complete conduit termination assembly wherever a locked and sealed connection is required.

The LNS200I is suited for use in 2-inch conduit terminations on electrical enclosures, panel boards, junction boxes, and similar metallic enclosures. Its sealing design makes it appropriate for installations where moisture ingress at conduit entry points must be controlled, including wet locations, outdoor panels, and industrial environments subject to wash-down or condensation. It fits within standard conduit assembly workflows alongside compatible bushings and connectors.

Key Features

• 2-inch trade size fits standard 2-inch conduit termination points
• Steel construction provides mechanical strength and resistance to physical damage
• Sealing design helps restrict moisture and contaminants at conduit entry points
• Locknut profile ensures secure, vibration-resistant engagement with enclosure knockouts
• Compatible with common conduit fitting assemblies used in panel and enclosure terminations

Compatibility

Designed as an OEM-style replacement or new-installation sealing locknut for 2-inch conduit termination applications on standard metallic electrical enclosures and panel boards.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements for conduit terminations. De-energize all circuits and lock out the enclosure before beginning any conduit termination work. The locknut should be tightened firmly against the enclosure wall using appropriate conduit tools to ensure a secure, low-resistance bond and an effective seal. Do not overtighten to the point of distorting the enclosure knockout or compromising the sealing element.
