Hubbell HBL6080OS FS Box 3/4 Knockouts — Product description

Robust Protection for Demanding Marine Environments

Engineered for the harshest conditions, this shallow weatherproof box stands up to constant exposure to saltwater spray, rain, and corrosive elements commonly found on docks, boats, and outdoor installations. Crafted from rugged black phenolic material, it provides superior insulation and impact resistance, ensuring your electrical connections remain secure and dry even in brutal weather. Unlike standard plastic enclosures that crack under UV exposure or temperature swings, phenolic construction delivers long-lasting durability without fading or warping.

Key Advantages Over Traditional Boxes

  • Seamless Waterproof Seal: Designed to prevent moisture ingress, protecting wiring and devices from short circuits and failures.
  • Easy Customization: Two pre-molded 3/4-inch IPS knockouts allow quick adaptation for conduit runs, saving installation time.
  • Compact Yet Spacious: With 16 cubic inches of capacity, it accommodates standard devices while fitting tight spaces on bulkheads or decks.
  • Non-Conductive Safety: Phenolic composition eliminates electrical hazards, ideal for high-humidity marine settings.

Ideal Applications in Marine and Outdoor Settings

Perfect for mounting receptacles, switches, or junction points on pleasure crafts, commercial vessels, piers, or seawalls. Its shallow profile hugs surfaces without protruding awkwardly, maintaining a clean deck layout. Contractors appreciate how it simplifies retrofits on older boats where space is at a premium, while the molded knockouts align flawlessly with standard marine conduit fittings.

Streamlined Installation for Pros and DIY Enthusiasts

Knock out the 3/4-inch hubs with a simple punch tool, thread in your conduit, and secure the box using the integrated mounting ears. Pair it with marine-grade gaskets and covers for a NEMA 3R-rated assembly that laughs off pounding waves. Always ground properly and test for watertightness post-install—common pitfalls like overtightened screws can compromise seals, so hand-tighten first.

Pro Tip: In salty environments, apply a thin dielectric grease to knockout edges before fitting conduit to block corrosion from the start.
