The VALUE COLLECTION BD-17495 is a steel reducing washer designed to adapt knockout openings in electrical enclosures from a larger conduit size to a smaller one. Specifically sized for a 1-1/4 inch to 1 inch reduction, this washer seats around the conduit entry point to fill the gap left when a smaller conduit or fitting is installed in a larger knockout. It is a standard component in commercial and residential electrical rough-in work, used by licensed electricians and electrical contractors wherever conduit enters panels, junction boxes, or enclosures.
This reducing washer is suited for use with rigid metal conduit, intermediate metal conduit, and thinwall conduit (EMT) applications. It is a common fitment in new construction, retrofits, and panel work where conduit sizes must transition at enclosure knockouts. The washer installs directly into the knockout before the conduit fitting is secured, providing a clean, code-compliant closure around the conduit entry.
Designed for use with rigid conduit, intermediate conduit, and thinwall conduit at 1-1/4 inch to 1 inch knockout transitions in standard electrical enclosures.
Installation is performed by a licensed electrician in accordance with applicable NEC requirements for conduit entries into electrical enclosures. Power down and de-energize the enclosure fully before opening or working near any panel or junction box. The reducing washer is placed into the knockout opening prior to installing the conduit connector or locknut. Ensure the washer seats flush and the conduit fitting is properly secured to maintain the integrity of the enclosure entry.
