Mushroom Vents - Low Domed Pattern

(No reviews yet) Write a Review


Smaller low-profile mushroom ventilators with a domed profile.  Cast in bronze, these UK-made vents have a low spigot and are ideal for mounting flush to cabin tops and other areas unlikely to become awash.

Their low, domed-profile means sheets will not catch on the vents when closed. The ventilator can be operated externally or from within with the interior thumb screw.

Available in polished bronze or chrome-plated bronze.
