Marinco FS Box Black f/15A, 20A, 30A Receptacles

The Marinco FS Box Black for 15A, 20A, 30A Receptacles (MPN 6080) is the weatherproof electrical enclosure every serious boater needs on deck or dockside. After years on the water, you'll recognize this as the standard that keeps your vessel's power connections protected from salt spray, rain, and UV degradation—critical when your shore power or generator connections are exposed to the elements. This non-metallic black box handles single or multiple receptacle installations, making it ideal for retrofit projects, new builds, or replacing corroded housings on aging systems.

Construction centers on durable non-metallic material that resists corrosion where aluminum or steel would oxidize within a season in marine environments. The FS Box accepts standard 15-amp, 20-amp, and 30-amp shore power receptacles, the three most common amperage ratings found across recreational vessels. Two 3/4-inch knockout holes provide flexible entry points for electrical conduit, allowing installers to route conductors from below-deck distribution panels without forcing awkward bends that compromise wire integrity. The box also accepts 7420CR weatherproof covers, an essential accessory that shields receptacles when lines aren't connected—preventing water ingress and extending component lifespan significantly.

This enclosure suits cruising boats, center consoles, fishing platforms, and permanent installations where shore power reliability matters. Compact dimensions (6 x 4 x 10 inches) fit bulkhead spaces without consuming valuable cabin real estate, while the 0.6-pound weight makes installation straightforward for single-handed deck work. Marinco's reputation for marine-grade reliability ensures connections stay dry and operational season after season, whether your boat sees weekend use or year-round service in harsh saltwater conditions.
