Designed to match the Opal hatches, Opal portlights also feature some unique benefits :
- Perfect watertightness with a one-piece thick frame section and double contact seal system
- One model only accepts an extensive range of wall thickness:
5 to 33 mm for opening portlights
8 to 33 mm for the fixed portlight
- Optimum visibility thanks to a nonobstructive position of the handle.
