Set of two 3inch (83 x 83 x 15 mm) black louvered marine vents designed for reliable hull and enclosure ventilation. Why you need these vents Reduce moisture and mildew: continuous airflow helps keep cabins, lockers, and storage spaces drier and fresher, reducing odor and corrosion risk. Protect interior gear: proper ventilation prevents trapped moisture that can damage cushions, lines, electronics, and stored equipment. Weatherresistant performance: built from durable plastic that withstands sun, saltwater, and changing temperatures for seasonafterseason use. Key features and benefits Optimized airflow: straightthrough design for vent hoses allows maximum air passage to improve circulation without restricting flow. Rain and debris protection: angled louver system prevents rain spray and stray debris from entering while still permitting air exchange. Durable construction: weatherresistant plastic retains function under marine conditions—UV exposure, salt spray, and temperature swings. Easy installation: each ventilated panel measures 83 x 83 x 15 mm and fits typical marine applications; can be mounted quickly to hulls or enclosures using standard tools. Universal compatibility: 3inch nominal size and straightthrough configuration work with common vent hose systems and general marine ventilation needs. Quantity and finish: two vents included, finished in black to blend with most hull and deck surfaces. Practical use scenarios Cabin and berth ventilation while underway: attach to vent hoses to bring fresh air into sleeping and living areas and reduce condensation. Locker, lockerbox, or anchor well airflow: install on lockers and storage compartments to limit moisture buildup and mildew on stored gear. Hull or enclosure ventilation for equipment spaces: use on enclosed compartments where passive airflow is needed without allowing rain entry.
