Rutgerson manufactures portlights for both motor and sailing boats. The flexible construction means that the portlights fit hulls from 8 mm (0.32") to 66 mm (2.6") thick.
The materials have been very carefully selected: special Swedish stainless steel,
silicone rubber seals of the very highest quality, sturdy and resilient acrylic glass.
This is why Rutgerson put safety first during the process of manufacturing portlights.
