Dottie RW42 Washer, 1-1/4" 3/4" Reducing Washer

Make knockout reduction simple and reliable with the Dottie RW42 reducing washer. Designed specifically for metal enclosures and sheet metal boxes, this reducing washer converts a 1-1/4 knockout to a 3/4 opening, enabling neat conduit feeds and secure connections for security, surveillance, and monitoring systems. Constructed from carbon steel with a galvanized finish and a 1.25 inch diameter, the RW42 resists corrosion and stands up to the demands of network cabinets and outdoor enclosure housings.

Beyond size reduction, the flat washer design cushions cable entries to prevent abrasion and strain on low-voltage wiring and camera cabling. Supplied in a pack of 50, it is a cost-effective choice for installers and facility managers who stock parts for repeated deployments. Environmentally friendly and RoHS compliant—see product listing for California Proposition 65 details—the Dottie RW42 balances durability with regulatory considerations.

Ideal for security camera mounts, access control enclosures, and structured cabling panels, this reducing washer speeds installation and improves long-term reliability. Add the Dottie RW42 to your next build or order stock for maintenance and replacement.
