Dottie R370 3-1/2" X 2" Reducing Bushing for Cable Management

Optimize conduit transitions and safeguard critical cabling with the Dottie R370 reducing bushing. This cable grommet and bushing is designed to convert a 3-1/2" threaded opening to accept a 2" conduit, delivering a clean, professional cable entry that minimizes wear and prevents pull-through. Built from durable zinc alloy, the R370 provides long-lasting mechanical protection for security, surveillance and monitoring cabling as well as networking and low-voltage systems.

Specifically engineered for use with Rigid/IMC conduit, the R370 features a 3-1/2" x 2" size and a 2" diameter interface to ensure a snug, code-compliant fit. Installers benefit from faster deployments and fewer field adjustments, while facility managers get reliable performance that reduces maintenance calls. Ideal for camera mounts, access control, and structured cabling pathways, this reducing bushing helps maintain signal integrity and prolong cable life.

Replace improvised adapters with a purpose-built solution that improves cable management and site aesthetics. Add the Dottie R370 to your next security, surveillance or networking project for a simple, effective conduit reduction—order now or specify it on your next job.
