Electricians and DIYers, these reducing washers are a simple but super useful little hardware item. They're designed to shrink a knockout hole in a steel electrical box or metal enclosure from 3/4 inch down to 1/2 inch. Made from galvanized steel, they're sturdy and corrosion-resistant. You typically use one washer on the inside and one on the outside of the hole to securely hold conduit or cable connectors in place. This pack comes with 100 washers, so you'll have plenty for multiple jobs or to keep in your toolbox. They're a lifesaver when you're adapting existing boxes or cabinets to fit smaller conduits without having to replace the whole enclosure. Whether you're wiring a new build, renovating, or just doing some electrical repairs, these washers make the job cleaner and more secure. Keep a pack on hand—you'll be surprised how often they come in handy. Practical, affordable, and essential for neat electrical work.
