Mulberry 40010 Galvanized Steel Reducing Washer, 1-1/4-Inch x 1-Inch Trade Size

Mulberry 40010 Galvanized Steel Reducing Washer, 1-1/4-Inch x 1-Inch Trade Size

The Mulberry 40010 Galvanized Steel Reducing Washer is a 1-1/4-Inch x 1-Inch trade size fitting engineered to adapt conduit connectors and fittings to knockout openings that do not match the connector size. Constructed from galvanized steel, this reducing washer provides a corrosion-resistant, durable solution for aligning a smaller conduit fitting within a larger panel, box, or enclosure knockout. It is a straightforward, cost-effective way to reduce a 1-1/4-Inch knockout down to accept a 1-Inch conduit connector without replacing the enclosure or drilling a new opening. Reducing washers like this one are a common staple in electrical panel work, junction box installations, and conduit runs where mismatched knockout and connector sizes are common on the job site.

Key Features

• Trade Size: 1-1/4-Inch x 1-Inch reducing washer allows a 1-Inch conduit fitting or connector to be securely seated in a larger 1-1/4-Inch knockout opening.
• Durable Construction: Galvanized steel material resists rust and corrosion, supporting long-term performance in both indoor and outdoor electrical installations.
• Reducing Washer Design: Flat, ring-style washer profile fits between the conduit connector locknut and the enclosure wall, closing the gap created by an oversized knockout opening.
• Simple Field Installation: Slips over the conduit connector threads before the locknut is applied, requiring no special tools for a secure, properly seated fit.
• Corrosion-Resistant Finish: Galvanized steel coating helps protect the washer from moisture and general environmental exposure over the life of the electrical installation.
• Versatile Sizing: The 1-1/4-Inch x 1-Inch reduction accommodates a common mismatch between conduit connector size and enclosure or box knockout size.
