This round openable nylon porthole is intended for mounting in the hull or panel of a boat. The white version has an external dimension of Ø 270 mm and provides a clear opening of Ø 185 mm.
The porthole features a nylon frame and a plexiglass pane. The round, openable design allows the porthole to be opened, while the closure is operated with wing knobs.
Installation requires a circular cutout of Ø 215 mm. The collar supports a panel or hull thickness of 6–35 mm, which should be verified against the intended mounting location prior to installation.
The external dimension, the clear opening, and the cutout size describe different parts of the installation: Ø 270 mm is the external dimension of the porthole, Ø 185 mm is the usable opening, and Ø 215 mm is the required mounting cutout.
