Southwire LRB7 Steel Reducing Bushing 1-1/4 X 1 Inch

Product Description

The SOUTHWIRE LRB7 is a steel reducing bushing designed to transition between two different conduit trade sizes in an electrical raceway system. It steps down from a 1-1/4 inch opening to a 1 inch opening, allowing electricians to adapt larger conduit knockouts or fittings to smaller conduit runs without the need for additional couplings or locknuts. The bushing is constructed from steel, providing the mechanical strength and durability required in commercial and industrial electrical installations. Licensed electricians and electrical contractors install this fitting as part of a code-compliant conduit assembly.

This reducing bushing is suited for use in standard conduit installations where knockout or fitting size mismatches must be resolved at panel enclosures, junction boxes, or conduit bodies. It fits into existing conduit openings and accepts conduit from the smaller end, making it a common part of panel rough-in work and raceway extensions in both residential service work and light commercial electrical projects.

Key Features

• Steel construction for mechanical durability in conduit systems
• Reduces from 1-1/4 inch to 1 inch trade size
• Compact profile at 0.688 inches in length fits tight enclosure entries
• One year limited warranty
• Also referenced as MADISON LRB-7 and TOPAZ RB7 for cross-reference sourcing

Compatibility

This fitting is cross-referenced with MADISON LRB-7 and TOPAZ RB7. Designed as an OEM-style replacement reducing bushing for standard 1-1/4 inch to 1 inch conduit fitting applications in electrical raceways.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for conduit fittings and raceways. De-energize and lock out the panel or enclosure before installing or removing any conduit fitting. Thread the bushing into the larger opening by hand and tighten with the appropriate fitting tool — avoid overtightening steel bushings in aluminum enclosures to prevent thread damage.
