Product Information
The Fantasea FML FNX Converter 55G is an adapter that lets you mount FNX lens ports and port accessories, or third-party lens ports and port accessories that share a similar mounting system, onto housings or port accessories built on the Fantasea FML port system. It is built from hard anodized aluminum alloy, depth rated to 60 meters (200 feet), and weighs 289 g (10.2 oz).
