This round openable nylon porthole is a black model with an outer diameter of 320 mm. It is designed for installation in hulls, walls, or panels and provides a clear opening of Ø 235 mm.
The porthole is made of nylon and fitted with a plexiglass pane. The openable design is secured with wing nuts, which hold the pane in the closed position.
Installation requires a circular cutout of Ø 265 mm. The porthole is suitable for hull, wall, or panel thicknesses from 6 to 35 mm. The outer diameter of Ø 320 mm describes the total dimensions of the porthole, while Ø 235 mm is the clear opening after installation.
The clearly distinguished outer dimensions, cutout dimensions, and opening dimensions make it possible to check the space requirements before installation. Check both the cutout diameter and the material thickness before mounting.
