Made of cast aluminum Almag-35, these sturdy, traditional style hatches are perfect for the deck of any boat. The tinted Lexan provides privacy while allowing plenty of light to shine through. Two bars support the Lexan. Aluminum Almag-35 and stainless steel hardware. The C150 hatch is curved to fit the crown of a deck. The deck flange rises 1/4" in the center which will accept most crowned decks. Caulking compound easily fills any differences. Color: Black, Dogs: 4, Opening: 24"x24", Flange: 27-1/8"x27-1/8"
