Reducing Washer, 1 x 1/2", Steel

Arlington Industries Plated Steel Reducing Washers provide a rugged, code-compliant solution for adapting oversized electrical enclosure knockouts to smaller conduit fittings. Designed to work in pairs (one for the inside and one for the outside of the enclosure wall), these heavy-duty washers allow electrical contractors to bridge size gaps instantly without replacing the box or panel. Whether correcting an oversized field-punched hole or adapting a multi-size factory knockout, Arlington's precision-stamped steel washers give the locknut a perfectly flat, robust bearing surface that resists deformation under extreme clamping loads.
