Thomas Betts 147 Conduit Locknut 2-1/2 in Rigid Imc

Product Description

The THOMAS BETTS 147 is a malleable iron conduit locknut designed to secure rigid and intermediate metal conduit (IMC) fittings to enclosures, panels, and junction boxes. At a 2-1/2 inch trade size, this locknut uses a threaded connection to lock conduit connectors firmly in place, preventing loosening from vibration or mechanical stress. The non-insulated design is rated for non-hazardous area installations. Licensed electricians and electrical contractors use this hardware as a standard component in commercial and industrial conduit runs where rigid or IMC conduit is specified.

This locknut is suited for use in rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems at the 2-1/2 inch trade size. Typical applications include securing conduit to metal enclosures, distribution panels, pull boxes, and similar electrical equipment. The malleable iron construction provides durability in demanding install environments. It is commonly used in commercial, industrial, and institutional electrical construction where threaded rigid or IMC conduit is the raceway of choice.

Key Features

• Malleable iron construction for strength and resistance to mechanical stress
• Threaded connection provides secure, tool-tightened engagement
• Non-insulated design for standard non-hazardous area use
• Compatible with both rigid metal conduit (RMC) and intermediate metal conduit (IMC)

Compatibility

Designed as an OEM-style replacement and standard-use locknut for 2-1/2 inch trade size rigid metal conduit and intermediate metal conduit (IMC) threaded fittings in non-hazardous area electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and lock out power to the panel or enclosure before beginning conduit termination work. Thread the locknut onto the conduit connector and tighten securely against the enclosure wall using a locknut wrench or hammer and screwdriver to ensure a solid mechanical and electrical bond. Do not overtighten to the point of cracking the fitting.
