Thomas Betts 604-TB Conduit Reducer 1-1/4 to 1/2 Inch Rigid Imc

Product Description

The THOMAS BETTS 604-TB is a threaded steel conduit reducer designed for use with rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems. It reduces a 1-1/4 inch trade size conduit entry down to a 1/2 inch trade size, allowing electricians to transition between conduit sizes at junction boxes, enclosures, and conduit bodies. Constructed from steel with a non-insulated design, this reducer is rated for use in non-hazardous locations. The threaded connection ensures a secure mechanical fit consistent with standard conduit installation practices.

This reducer is suited for commercial and residential electrical installations where IMC or rigid conduit systems require a size transition. Typical applications include panel enclosure knockouts, conduit body entries, and junction box fittings where a change from 1-1/4 inch to 1/2 inch conduit is needed. It is installed by licensed electricians as part of a complete conduit assembly and is appropriate for dry, damp, or wet locations consistent with the conduit system rating.

Key Features

• Reduces 1-1/4 inch trade size to 1/2 inch trade size in a single fitting
• Compatible with rigid metal conduit (RMC) and intermediate metal conduit (IMC)
• Threaded connection for secure, standard-compliant mechanical assembly
• Steel construction for durability in demanding installation environments
• Non-insulated design for use in non-hazardous area applications

Compatibility

Designed as an OEM-style fitting for use with rigid metal conduit and intermediate metal conduit (IMC) systems requiring a 1-1/4 inch to 1/2 inch trade size reduction with threaded connections.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits and verify power is off before working on any conduit assembly. Hand-tighten the threaded fitting first, then use an appropriate conduit wrench to complete engagement without over-stressing the threads. Ensure the conduit system's overall rating for location type is maintained after installation.
