Introducing our Low Profile Mushroom Vent, meticulously crafted from durable sheet 304 stainless steel. Designed for a water-tight seal when closed, it features a rubber gasket and threaded stem connecting the lid to the base, ensuring robust protection against water ingress. The securely mounted base, with the stem extending through your deck cutout, allows for easy operation to open or close the vent as needed.
With a stainless mesh screen inside, these vents offer versatile functionality, seamlessly integrating inside our dorade boxes, combining with other ventilation systems, or serving as standalone units. Crafted with a rounded dome reminiscent of a mushroom, these vents effectively repel water, safeguarding your boat from moisture infiltration.
Available in sizes ranging from 3" to 5", our mushroom vents provide flexibility to meet various vessel requirements, ensuring optimal ventilation and protection for your boat.
