Dottie R375 4" X 3" Reducing Bushing, Cable Management

Make neat, secure conduit transitions in security, surveillance and monitoring installations with the Dottie R375 reducing bushing. Designed as part of Dottie’s Cable Grommets & Bushings line, this reducing bushing converts a 4" threaded opening down to 3" (3" diameter accept), letting you adapt Rigid/IMC conduit to smaller conduit runs without custom fittings. Constructed from a robust zinc alloy, the R375 resists corrosion and mechanical wear so your cable runs stay protected over the long term.

For integrators and electricians working on security camera mounts, access control, or low-voltage networking, the R375 streamlines installation by reducing need for multiple parts and protecting cable jackets during pull-through. Its threaded fit delivers a secure, vibration-resistant joint ideal for high-traffic or outdoor enclosures. Use the Dottie R375 to improve job-site efficiency, reduce touch-ups, and maintain tidy, code-compliant conduit entries. Add the R375 to your toolkit for faster, cleaner installs in surveillance, monitoring and networking applications — order today and simplify your next project.
