Value Collection BD-17490 Reducing Washer Steel 3/4 to 1/2 in

Product Description

The VALUE COLLECTION BD-17490 is a steel reducing washer designed to adapt a larger knockout opening to a smaller conduit fitting inside electrical enclosures and junction boxes. It steps down a 3/4-inch knockout to accept a 1/2-inch conduit connector, providing a clean, secure fit without leaving exposed gaps around the fitting. This type of hardware is a standard staple on electrical jobs where box knockouts do not match available conduit sizes. Electricians and electrical contractors install these during rough-in and trim-out on both new construction and retrofit work. Each package contains 100 washers.

This reducing washer is suited for use with rigid metal conduit, intermediate metal conduit, and thinwall conduit (EMT) in commercial and residential electrical installations. It is commonly used wherever a panel, enclosure, wireway, or junction box has a 3/4-inch knockout and the conduit run requires a 1/2-inch connection. The steel construction holds up in dry, damp, and standard indoor service environments typical of these conduit systems.

Key Features

• Reduces 3/4-inch enclosure knockouts to accept 1/2-inch conduit fittings
• Compatible with rigid conduit, intermediate conduit, and EMT thinwall conduit
• Steel construction for durability in standard electrical enclosure applications
• 100-piece package quantity suits job-site stocking and bulk installation work
• Straightforward drop-in installation with no special tooling required

Compatibility

Designed for use with rigid metal conduit, intermediate metal conduit, and EMT thinwall conduit systems requiring a 3/4-inch to 1/2-inch knockout reduction in electrical enclosures, panels, and junction boxes.

Installation Notes

Installation is performed by licensed electricians in accordance with applicable NEC requirements for conduit fittings and enclosure entries. Power down and lock out the enclosure before working on any box or panel. Seat the reducing washer flush in the knockout before threading the conduit connector through to ensure a secure, rattle-free fit. Inspect the washer for burrs or deformation before installation to avoid damage to conductor insulation.
