Southwire LRB16 Steel Reducing Bushing 2x1-1/2 in

Product Description

The SOUTHWIRE LRB16 is a steel reducing bushing designed to transition conduit or knockout openings from a 2-inch fitting to a 1-1/2-inch fitting. Reducing bushings are standard electrical fittings used to adapt larger threaded openings to accept smaller-diameter conduit or connectors without requiring a new enclosure. This bushing is constructed from steel for durability in commercial and residential electrical installations. Licensed electricians and electrical contractors install these fittings during panel, junction box, and enclosure work where mismatched knockout sizes must be adapted.

This fitting is used in conduit systems where a 2-inch threaded hub or knockout must be reduced to accept a 1-1/2-inch conduit connection. Common installation scenarios include electrical panels, metal enclosures, junction boxes, and conduit bodies in both residential and light commercial applications. This part is also referenced under the Topaz part numbers RB-16 and RB16, and the Madison part number LRB-16, making it a widely recognized cross-reference in the electrical supply trade.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the panel or enclosure before working inside any electrical box. Thread the bushing into the larger knockout hub by hand first, then tighten with the appropriate strap wrench or bushing tool — do not use pliers on the bushing face. Inspect the threads on both the bushing and the hub for damage before final installation.
