Dottie RW93 Washer, 3-1/2" 1" Reducing Washer

Make enclosure wiring faster and more reliable with the Dottie RW93 reducing washer. Designed to convert a 3.5 in knockout down to a 1 in opening, this Dottie washer simplifies conduit and connector installation for security, surveillance, monitoring, and network equipment. The galvanized carbon steel construction resists corrosion in indoor and sheltered outdoor enclosures, while the embossed size marking and raised flange centralize the knockout for quick, accurate alignment—reducing rework on camera housings, junction boxes, and rack-mounted enclosures.

Because the RW93 protects cable jackets and smooths sharp sheet-metal edges, it helps prevent abrasion and signal issues on CCTV, network, and monitoring cabling. Each pack contains 10 washers (model RW93), offering the right quantity for routine installations and service calls. RoHS and California Proposition 65 compliant, this reducing washer meets common environmental requirements for commercial projects.

Ideal for security installers, low-voltage contractors, and IT teams, the Dottie 3-1/2 in x 1 in reducing washer delivers a durable, time-saving solution for enclosure knockouts. Add the RW93 10-pack to your next order to streamline camera, sensor, and networking installs.
