The aluminum frame of the hatch is designed with a smooth and flowing appearance, and is completely seamless at the corners. The aluminum profile is slightly thicker than our Low-profile hatch, for additional strength, but is still only 30mm wide, and only projects 30mm above the deck surface. The hidden hinges make our low-profile hatches smoother, and therefore safer, on the deck of your yacht. The aluminum frame is anodized, and inset with smoky gray Acrylic glass. The opening angle of the hatch is 0-180 degrees and can be easily opened with the handles from both outside and inside. Of course, there are also safety-locks that can only be operated from inside our hatches, to ensure your security. Usually the smaller hatches don' t need stainless-steel brace-struts, and therefore can be opened a full 180° angle. Hatches with stainless-steel bracing-struts can be opened 0-100° angle. Aluminium trim mouldings and black fly screens can be ordered separately.
