Marinco 6083CR FD Box w/¾" K.O. Holes

The Marinco 6083CR FD Box with ¾" K.O. Holes is the marine electrician's go-to solution for clean, code-compliant power distribution on boats and watercraft. Whether you're outfitting a new build, upgrading an aging vessel's electrical system, or maintaining a working boat, this fiberglass enclosure provides a reliable mounting point for standard shore power receptacles. Built to withstand the corrosive marine environment, this box accepts multiple amperage ratings—15A, 20A, 30A, and 50A receptacles—making it adaptable to both modest cruising sailboats and larger sportfishermen with serious electrical demands.

Constructed from marine-grade yellow fiberglass, the 6083CR resists UV degradation, saltwater corrosion, and the constant moisture exposure that breaks down lesser materials. The two pre-drilled ¾" knockout holes allow precise cutouts for receptacle installation, eliminating guesswork and reducing on-site modification time. The box is engineered to accept 7420CR and 7788CR covers, ensuring a weathertight seal that keeps spray, rain, and salt spray away from your electrical connections. At just one pound and measuring 6 × 3 × 9 inches, it's compact enough to fit tight galley or helm corners without consuming valuable marine real estate.

Seasoned boat owners and professional marine technicians rely on Marinco equipment because it's engineered for saltwater service and backed by marine-industry standards. This FD box is ideal for retrofit applications where existing wiring and breaker circuits need a new, code-compliant receptacle interface. Installation is straightforward: mount the fiberglass housing to a bulkhead or exterior panel, run your shore power or auxiliary supply lines through the knockouts, install your chosen amperage receptacle, and cap with the appropriate cover. For cruising boats, weekenders, and commercial vessels alike, the 6083CR FD Box delivers the durability and reliability you need when you're far from the slip.
