Dottie RW105 Washer, 4" 1-1/2" Reducing Washer

Make knockout resizing fast and reliable with the Dottie RW105 reducing washer. Designed for installers and facilities teams, this washer converts 4" knockouts down to a 1-1/2" opening so you can route cable and conduit cleanly through metal enclosures, cabinets, and sheet metal boxes. Constructed from carbon steel with a galvanized finish, the RW105 resists corrosion and stands up to the demands of security, surveillance, monitoring and networking environments.

Beyond size reduction, the washer protects cable jackets from sharp knockout edges, minimizing wear and potential signal issues in camera, access control, and network cabling runs. The flat-washer form factor installs quickly with minimal tools, lowering labor costs on site. Each pack includes 10 consistent fittings to streamline repeat installations across racks and enclosures.
