Material and durability: Made from stainless steel 316 (marine grade) for long-term performance and corrosion resistance. Ideal where durability and low maintenance matter. Corrosion protection: The back side is passivated to significantly reduce rust and staining over time, preserving the plate’s finished appearance in aggressive environments. Secure installation: Designed with a 5 mm edge mounting hole for easy screw fixing. Fits standard screw mounts and provides a stable, vibration-resistant attachment. Function and compatibility: Serves as a ventilation plate/vent cover for cabinets, enclosures, ducts or panels. Compact and unobtrusive design that integrates with a variety of metal, wood or composite surfaces. Performance benefits: Maintains airflow while protecting openings from debris and ensuring a clean, professional look. Resistant to salt air and moisture where ordinary steels would corrode. Use scenarios: 1) Marine and coastal boats: Install as a cabin or equipment ventilation plate where exposure to salt air requires marine-grade stainless steel. 2) Outdoor HVAC and electrical enclosures: Use to provide ventilation while protecting components from weather and corrosion. 3) RVs, caravans and utility cabinets: Add reliable airflow to storage compartments and service panels with a low-profile, durable cover. What you get: a robust stainless steel 316 ventilation plate with a passivated back surface and a 5 mm edge mounting hole for secure screw attachment — built to last in demanding conditions.
