Make knockout resizing fast and reliable with the Dottie RW54 reducing washer. Designed for installers and facilities teams, this Dottie washer converts a 1-1/2 inch knockout to a 1-1/4 inch opening, providing a secure, finished pass-through for cabling in metal enclosures, cabinets, and sheet metal boxes.
