Vetus MAG4633SL Magnus Deck Hatch CE A1 – 457 × 327 mm Cut-Out
The Vetus MAG4633SL Magnus deck hatch is engineered for ocean-going conditions, certified to CE Category A1 for installation in Area I of the vessel. Its heavy-duty flush-mounted design ensures minimal snagging on deck while supporting safe emergency access, ventilation, and natural lighting.
The hatch is built with a satin sheen anodized aluminium frame and a 10 mm dark-smoke framed acrylic pane, offering superior durability and reduced glare. The friction hinges allow stepless opening up to 180°, holding the lid open without requiring support stays.
