Reducing Washers

Shop reducing washers for adapting oversized knockout openings in electrical boxes, cabinets, panels, and metal enclosures. Electrical reducing washers allow a smaller conduit or fitting to pass through an opening originally made for a larger trade size.

This collection includes steel reducing washers in numerous opening and conduit-size combinations. These electrical hardware components are commonly used when installing rigid conduit, intermediate metal conduit, electrical fittings, and raceway systems in existing or newly fabricated enclosures.

Conduit reducing washers are typically positioned around a knockout opening to center the smaller fitting and create a more suitable connection point. They provide a practical option for adapting conduit entries without replacing the electrical box, cabinet, panel, or enclosure.

Reducing washers are used across telecom facilities, broadband projects, EV charging installations, data centers, commercial buildings, industrial facilities, and electrical infrastructure. They can support equipment installations involving control cabinets, junction boxes, power systems, cable-management enclosures, and other metal housings.
