Superior Stainless Steel Construction

Marine-Grade Materials: The HBL303SSO utilizes 316-grade stainless steel construction, providing exceptional resistance to chloride corrosion from saltwater exposure. This premium material maintains its appearance and structural integrity even in the harshest marine environments.

Traditional Aesthetics: The classic round design offers timeless appeal that complements traditional yacht styling and heritage marina installations. The polished stainless steel finish provides an elegant appearance that maintains its luster with minimal maintenance.

Corrosion Resistance: Stainless steel construction eliminates galvanic corrosion concerns and provides superior longevity compared to painted or coated alternatives. The material is immune to rust and maintains structural integrity throughout decades of marine service.

Advanced Weather Protection

IP56 Rating: The self-closing gasketed cover provides IP56 protection, meaning the outlet can withstand heavy seas and high-pressure water jetting without compromising electrical integrity. This exceeds the protection levels of many marine electrical components.

Self-Closing Design: The spring-loaded cover automatically closes when not in use, ensuring consistent weather protection even if operators forget to manually close the cover. This feature is critical for maintaining waterproof integrity in marine environments.

Gasket Sealing System: The integrated gasket creates a watertight seal when the cover is properly secured. The gasket material is selected for marine durability and maintains sealing effectiveness across temperature extremes and UV exposure.

Installation and Compatibility

Standard Mounting Pattern: The 2-3/8" center-to-center mounting holes match industry-standard patterns, facilitating easy installation in existing dock boxes or new construction projects.

Complete Hardware Package: Each outlet includes all necessary mounting hardware and gaskets, ensuring proper installation and immediate weather protection.

Professional Integration: The nickel-plated brass adapter plate allows mounting in FS (shallow) or FD (deep) marine-grade weatherproof dockside boxes, providing flexibility for various installation requirements.

ABYC Compliance and Safety

When properly installed as part of a complete shore power system, the HBL303SSO supports ABYC E-11 compliance requirements. The twist-lock design provides positive retention that prevents dangerous disconnections under load.

The stainless steel construction provides excellent grounding continuity when properly bonded to dock electrical systems, supporting safe operation and electrical code compliance.

Maintenance and Service Life

Low Maintenance: Stainless steel construction requires minimal maintenance beyond periodic cleaning and gasket inspection. The material won't rust, corrode, or require protective coatings.

Long Service Life: Premium materials and construction ensure decades of reliable service in marine environments. The outlet is designed to withstand constant exposure to salt spray, UV radiation, and temperature extremes.

Gasket Replacement: Periodic gasket inspection and replacement as needed maintains watertight integrity. The gasket design facilitates easy replacement without specialized tools.
