Vetus Escape Hatch, Libero, 19-11/16" x 14-9/16". The hatch can be opened from either inside or outside.
The hatch can be shut completely watertight, or secured with a small air gap to allow permanent ventilation.
An internal locking mechanism ensures the hatch cannot be opened from outside when the boat is left unattended. This operates in both the closed or ventilation positions.
The low external profile ensures that ropes, e.g. running rigging on sailing boats, cannot foul on the handles.
