Arlington Industries RW24 Reducing Washer 3 to 1 Inch

Product Description

The ARLINGTON INDUSTRIES RW24 is a reducing washer designed to adapt a 3-inch knockout or opening down to a 1-inch fitting. Reducing washers are standard hardware in electrical installations, used to close the gap around conduit fittings or connectors that are smaller than the knockout they occupy. This part ships as a single unit and is a common stock item for electricians working on panels, enclosures, junction boxes, and other electrical equipment requiring a clean, code-compliant knockout reduction.

This reducing washer is suited for residential and commercial electrical work where a connector or fitting does not match the knockout size. Electricians use reducing washers during new construction, panel upgrades, and service work to fill unused or oversized knockouts. The 3-inch to 1-inch reduction makes it appropriate for larger enclosures and distribution equipment where mixed knockout sizes are common.

Key Features

• Reduces a 3-inch knockout to accept a 1-inch fitting or connector
• Single-unit packaging for precise quantity control on the job
• Flat washer profile for flush seating in standard electrical enclosures
• Sized for use with standard conduit fittings and locknuts

Compatibility

Designed as an OEM-style replacement and standard-fit reducing washer for electrical enclosures, panelboards, and junction boxes with 3-inch knockouts requiring a 1-inch fitting reduction.

Installation Notes

Reducing washers are installed by licensed electricians in accordance with NEC requirements for securing fittings in enclosures. De-energize the panel or enclosure before working in or around any electrical box. Seat the reducing washer flush against the interior wall of the enclosure before threading the locknut, ensuring the fitting is secure with no movement. Do not stack multiple reducing washers to achieve a reduction not listed for this part.
