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.
