Newmar RA-1 Cable FEED-THRU 0.1-0.25 Inch Cable Diameter

The Newmar RA-1 Cable FEED-THRU is a right-angle waterproof feed-through fitting engineered for marine and boating applications where cables must route cleanly through vertical or horizontal surfaces. Whether you're running power lines, network cables, or sensor wiring through cabin walls, console panels, or hull penetrations, this fitting solves a critical problem: routing cables at 90 degrees without kinks, sharp bends, or damage. Built by Newmar, a trusted name in marine electrical solutions, the RA-1 keeps your boat's interior organized and safe while maintaining a professional appearance.

The RA-1 features a molded nylon construction that resists corrosion, salt spray, and UV exposure—essential qualities in the harsh marine environment. Its low-profile, wall-hugging design keeps cables pressed close to the surface, minimizing snags with personnel, equipment, and other onboard systems while reducing trip hazards and equipment interference. The fitting accommodates cable diameters from 0.1 to 0.25 inches, making it versatile for a range of standard marine wire gauges and bundled cable runs. The waterproof seal ensures that moisture, bilge water, and salt spray cannot compromise electrical connections, a critical safeguard on vessels where corrosion can disable systems quickly.

This fitting is ideal for center console boats, cabin cruisers, sailboats, and commercial fishing vessels—anywhere cables pass through bulkheads, cabinetry, or structural panels. The 90-degree routing is especially useful in tight spaces where straight runs are impossible, such as passing wires from a hardtop to electronics below deck or routing engine instrumentation through cabin walls. Installation is straightforward: drill or existing hole accepts the fitting, and the nylon construction requires no special tools. Boaters upgrading electronics, adding fish finders, GPS systems, or autopilot wiring will appreciate the RA-1's ability to maintain a clean, professional install that keeps systems dry and protected for years of reliable service.
