Professional Marine-Grade Cable Protection

Ensure your vessel's electrical integrity with the Airow Marine Midget Clam Shell Vent. Engineered from high-density AISI 316 Stainless Steel, this vent cover provides superior protection against saltwater corrosion and UV degradation, far surpassing standard 304 or plastic alternatives.

  • Mirror-Polished Finish: High-reflectivity surface resists tarnishing and enhances vessel aesthetics.
  • Splashproof Clamshell Design: Effectively shields cables, hoses, and wiring openings from direct water spray and debris.
  • Heavy-Duty Stamped Construction: Provides industrial-grade durability with a low-profile footprint suitable for decks, hulls, and cabinets.
  • Universal Application: Ideal for boats, yachts, RVs, and caravans requiring secure through-hull or panel cable routing.

Precision-measured at 2.3" x 2.2" with a 0.5" clearance, this 'Large' variant accommodates multiple wire looms or thicker hoses with ease.

Frequently Asked Questions

Will this vent yellow or crack like the plastic ones currently on my boat?
No. Unlike ABS plastic covers that become brittle and yellow under direct UV exposure, our 316 stainless steel is stamped from solid marine-grade metal that is impervious to UV damage and thermal cracking.
Is the opening large enough to fit a standard transducer cable connector?
Yes, this 'Large' variant features a 0.5-inch (13mm) vertical clearance, which comfortably accommodates most marine transducer cables and common wiring looms used in marine electronics.
Can I use this for ventilation in a battery box or locker?
While primarily used for wire and hose splash protection, the clamshell design allows for passive airflow, making it suitable for small locker ventilation where direct water ingress must be minimized.

Our Roots

Hong Kong Based, 8 Years of Expertise

The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories. These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
