The Vetus Magnus is a range of extra heavy duty hatches. These hatches are provided with friction hinges, which will keep the hatch open in almost any position, without the need for stays. The hatch can be opened through 180° and there are virtually no obstructions in the hatch opening. Like other VETUS hatches, the Magnus range can be opened from inside or outside of the boat. They can also be left locked; either completely watertight or in a ventilation position and the frame profile is satin sheen anodized. The acrylic has a thickness of 10mm and the color is “dark smoke”. The aperture dimensions (cut-out sizes) of Magnus hatches conform with many of those that are current in the market. These Vetus Magnus Hatches are CE classified: A I, which means to say that they are designed for ocean use and can be fitted on deck.
