Garmin 20 ft GMS10 Marine RJ45 Cable – Onboard Networking for Marine Electronics

Overview

On the water, dependable connections matter as much as precise charts. The Garmin 20 ft GMS10 marine RJ45 cable is built to help onboard networks stay aligned, with RJ45 ports at both ends and screw collars that resist loosening through movement and vibration. The included hole plug gives you a tidy option to seal unused ports, helping to keep salt air and debris from affecting sensitive gear. The result is a compact, user friendly cable that blends into a shipboard setup while delivering straightforward, dependable connectivity.

The 20-foot reach provides flexibility for laying out a network across a helm station, equipment rack, or beneath deck panels. RJ45 connections at each end support common marine networking gear, while screw collars offer a hands-on way to secure cables in place during rough conditions. The plug and play nature of this accessory makes it a practical addition to a boatside toolkit, designed to simplify installation without sacrificing performance. The package weight and dimensions speak to a compact, easy-to-handle component that integrates smoothly with other marine electronics.
