This 4 inch butterfly ventilation plate is a round air gill designed for controlled air circulation in marine, caravan and recreational applications. The manual side knob allows simple thumb-operation to open and close the flap, giving you easy regulation of airflow without tools.
Built from 304 stainless steel with mirror-polished finish, the vent resists corrosion and salt spray exposure. The 1mm thickness (0.8mm vent flap) provides durability in demanding marine environments.
Suitable for boats, yachts, caravans, campers, garden sheds, garages, barbecue barrels and smokers. The neat finish and simple design integrate into most installations without drawing attention.
Diameter: 102mm (4 inches). This pack contains two units.
