Seachoice 50-10021 Weatherproof Cable Outlet – 5/16" Chrome-Plated Brass
A compact, watertight cable outlet designed for routing slightly larger wires and cables cleanly through boat bulkheads, transoms, and panels. The chrome-plated brass construction resists corrosion in saltwater environments, while the threaded cap and rubber gasket create a reliable weatherproof seal — keeping moisture out and your wiring neat. The 5/16" outlet diameter accommodates a wider range of cable sizes than the 1/4" version, making it a versatile choice for thicker instrument cables, power leads, and multi-conductor runs.
Key Features
- Watertight design — threaded cap and rubber gasket seal against moisture ingress
- Chrome-plated brass construction for corrosion resistance
- 5/16" cable outlet diameter — suits thicker marine cables and multi-conductor runs
- 1-1/4" base diameter for secure panel or bulkhead mounting
- Clean, professional finish for helm panels and console installations
- Part number: 50-10021
Parts Desk Insights
Best use case: Choose the 50-10021 over the 1/4" version when you’re routing thicker cables — such as power leads, multi-conductor instrument cables, or heavier-gauge wiring — through a bulkhead or transom. The 5/16" outlet gives you the extra clearance needed for cables that won’t fit through the smaller 1/4" fitting without stripping or damaging the jacket. It’s a common fit for helm console builds, electronics installations, and engine compartment wiring runs where a clean, sealed entry point is required. If you need the smaller 1/4" outlet version, see the Seachoice 50-10011 Weatherproof Cable Outlet – 1/4".
