Blue Sea 2204 Red Terminal Feed Through Connector

The Blue Sea 2204 Red Terminal Feed Through Connector is a marine-grade electrical component designed to safely pass high-current cables through hulls, decks, and bulkheads without chafing or signal degradation. Built by Blue Sea Systems, a brand trusted in marine electrical systems, this connector eliminates the cable damage that standard protective grommeting alone cannot prevent.

Large-diameter cables routed through structural penetrations are inherently vulnerable to abrasion, even with grommet protection. The 2204 feed-through connector addresses this by providing a dedicated passage point that isolates the cable jacket from sharp edges and creates positive strain relief at the hull or bulkhead interface. The red-colored terminal design aids in circuit identification and polarity management in complex electrical systems common on fishing vessels, cruising sailboats, and offshore platforms. Compact dimensions (3 x 2 x 5 inches) and lightweight construction (0.3 lbs) make installation straightforward in tight engine rooms or cabin spaces.

This connector suits both weekend anglers upgrading auxiliary power systems and serious offshore operators managing multi-bank battery banks, thruster wiring, or high-amperage charging circuits. It's equally relevant for live-aboard cruisers, commercial fishing fleet maintainers, and anyone running upgraded electrical loads—radar systems, windlasses, DC refrigeration, or auxiliary charging—that require safe cable routing through structural barriers. Terminal feed-through connectors are essential components in marine electrical code compliance and extend the service life of expensive marine wiring by preventing the chafing damage that leads to shorts, fires, and system failures.
