Heavy duty portholes

These heavy duty portholes are tested acc. to EN ISO 12216, A1 which means they are suitable for use in the hull side. They have a 10 mm opening pane in the colour “smoke”. The pane is set in an aluminium frame. The portholes are fitted with friction type hinges, permitting them to stay open in any position. Two large diameter knobs ensure that the portholes can be closed completely watertight.

The aluminium frame is satin anodized and the clamp type installation ensures that no fixings are visible internally or externally. Different dimension portholes are also available to special order.

All AI portholes are supplied with a composite mosquito screen as standard.
