L H Dottie Co RW63 Reducing Washer 2 to 1 Inch

Product Description

The L H Dottie Co RW63 is a reducing washer designed to step down a 2-inch knockout or opening to accept a 1-inch conduit fitting or connector. Reducing washers are a standard solution for electrical enclosure work, allowing technicians to use a smaller fitting or connector in a larger pre-punched or field-cut opening without replacing the box or panel. This hardware accessory is a single-piece unit sold individually and is a common stock item on service vans and in panel shops handling conduit termination work.

This reducing washer is used in electrical panels, junction boxes, conduit bodies, and enclosures where knockout sizes do not match the conduit or fitting being installed. It is typically installed during rough-in or trim-out stages of electrical work in both residential and commercial applications. Electricians and electrical contractors rely on reducing washers to maintain a clean, code-compliant termination when mixed knockout sizes are present on a single enclosure.

Key Features

• Steps down a 2-inch opening to a 1-inch fitting or connector
• Standard reducing washer form factor for electrical enclosure use
• Sold as a single unit for precise quantity control on the job
• Compatible with common conduit termination hardware and connectors

Compatibility

Designed as an OEM-style replacement and standard hardware accessory for use with 2-inch knockouts requiring a 1-inch conduit fitting or connector in electrical enclosures and boxes.

Installation Notes

Reducing washers are installed by licensed electricians in accordance with NEC requirements for conduit terminations and enclosure integrity. De-energize and lock out the panel or enclosure before beginning any work inside an electrical box. Seat the washer flush against the knockout edge before threading the connector or fitting through to ensure a secure, rattle-free termination. Do not force or deform the washer during installation, as this can compromise the fit and code compliance of the termination point.
