Marine Stainless Steel Clam Shell Vent Cover

🔧 Solves Your Biggest Pain Points

• Water getting in through cable and wire exit holes? The curved clam shell hood deflects rain, spray, and wash-down water away from the opening — keeping your bilge, cabin, and electrical systems dry.
• Poor hull ventilation causing heat and moisture buildup? The open-bottom design allows passive airflow through the hull — wind-driven air circulates naturally without any power required.
• Cheap plastic vents corroding or cracking? Marine-grade stainless steel with mirror-polished finish is completely rust-proof, corrosion-resistant, and maintains its premium appearance season after season.
• Complicated installation? Three pre-drilled mounting holes and a smooth screw-and-hole combination make installation fast and secure — screws included.
• Wrong size for your application? Available in two sizes — Small (1.54×1.77×0.47 in) and Large (2.05×2.13×0.67 in) — to fit different hull openings and cable diameters.
