Perfect water tightness with a one-piece thick frame section One model only accepts an extensive range of wall thickness: 5 to 33 mm Optimum visibility thanks to a non-obstructive position of the handle
Using a sole ergonomic handle, the portlight can be opened with one hand. The handle also evens out the pressure all around the seal and thus guarantees an excellent water-tightness.
The Opal portlights feature a lip seal system, ensuring perfect water tightness. The special shape of the seal allows it to be mounted in the frame, without any glue.
