Southwire LRB15 Steel Reducing Bushing 2x1-1/4 in

Product Description

The SOUTHWIRE LRB15 is a steel reducing bushing designed to adapt a larger conduit opening to accept a smaller conduit fitting. Reducing bushings are standard components in electrical conduit systems, allowing installers to transition between trade sizes without replacing knockout hardware. The LRB15 adapts a 2-inch opening down to a 1-1/4-inch fitting, making it a common item in panel, junction box, and enclosure rough-in work. Electricians and electrical contractors install these bushings during conduit layout and box termination. Constructed from steel, this bushing delivers the mechanical durability expected in commercial and residential electrical installations.

The LRB15 reducing bushing is used in standard conduit wiring systems where box or enclosure knockouts do not match the incoming conduit trade size. It seats into a 2-inch knockout and accepts a 1-1/4-inch conduit fitting or locknut. Typical installation scenarios include load centers, junction boxes, pull boxes, and enclosures across residential, commercial, and light industrial applications. This bushing is also cross-referenced as Madison LRB-15 and Topaz RB15 for sourcing and specification purposes.

Key Features

• Steel construction for mechanical strength and durability in conduit applications

Compatibility

Cross-referenced as Madison LRB-15 and Topaz RB15. Designed as an OEM-style replacement or direct substitute reducing bushing for standard 2-inch to 1-1/4-inch conduit knockout applications in electrical enclosures, junction boxes, and load centers.

Installation Notes

Installation is performed by licensed electricians in accordance with the National Electrical Code (NEC). De-energize the panel or enclosure completely before beginning conduit termination work. Thread or press the bushing into the 2-inch knockout before seating the 1-1/4-inch fitting or locknut. Verify that the bushing is fully seated and secure before pulling conductors through the conduit run.
