Thomas Betts 142SL Conduit Locknut 3/4 Inch Rigid Imc Steel

Product Description

The THOMAS BETTS 142SL is a steel conduit locknut designed to secure rigid metal conduit (RMC) and intermediate metal conduit (IMC) connections at enclosures, junction boxes, and panel knockouts. Sized for 3/4 inch trade size conduit, the 142SL uses a threaded connection to pull the conduit fitting tightly against the enclosure wall, establishing a solid mechanical bond. The non-insulated steel construction is rated for watertight area of application, making it suitable for installations where moisture resistance is required. Electricians install this hardware during conduit rough-in and final trim work on both commercial and residential projects.

The 142SL is used wherever 3/4 inch trade size rigid or IMC conduit terminates at a metal enclosure, disconnect, panel, or junction box. Typical install scenarios include service entrance work, branch circuit conduit runs, and equipment connections in industrial and commercial environments. The watertight area designation makes it appropriate for wet or damp location installations as defined by the NEC.

Key Features

• Threaded connection type for secure, reliable conduit termination
• Steel construction provides durability in demanding trade environments
• Non-insulated design for standard conduit locknut applications
• Rated for watertight area of application
• 3/4 inch trade size fits standard RMC and IMC conduit fittings

Compatibility

Designed as an OEM-style replacement and standard conduit fitting component for 3/4 inch trade size rigid metal conduit and intermediate metal conduit (IMC) systems.

Installation Notes

Install and service by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and lock out the panel before working at any enclosure knockout. Thread the locknut onto the conduit fitting and tighten firmly against the enclosure wall using channel-lock pliers or a locknut wrench to ensure full mechanical and electrical continuity. Do not overtighten to the point of deforming the enclosure wall or stripping the threads.
