Our range of Vetus PX Portholes are hand-polished with anodized aluminum frames, and “smoke” color acrylic panes of 3/8” thickness. For every PX porthole, a Vetus Mosquito Screen can be supplied. These Vetus PX portholes are not screwed, but clamped. Consequently, there is no need to drill holes. Simply select the most suitable porthole by finding the dimensions you require.
