Product details

These medium-profile hatches are identical in style to low-profile hatches, but are fitted with thicker acrylic glass and a reinforced frame. The hatches are suitable for the forcastle areas of larger ocean-going yachts. The new sealing system guarantees complete watertightness and replacing a damaged pane is easy. Friction hinges allow the hatch to be opened to a variety of positions. All hatches are internally fitted with lockable latches and can be opened from the outside. Trimkits are available as accessories for the clean inner closure with fly screens. CE approved.

Product is very well made and can be easily installed. I hope that the friction setting for the hatch opening lasts for a long time.
