Freeman Marine 18" round lift out hatch with aluminum ring. Freeman Marine 2400 Series Cast Aluminum Hatches are available in a variety of sizes and shapes. Standard models have a cast aluminum cover, aluminum dogging mechanism, and cast aluminum ring. Freeman Marine's uniformly spaced dogs are superior to the "yoke" or "strongback" type seal mechanisms which cause inherent cover distortion and sealing problems. Freeman 2400 Series Cast Hatches feature a stainless steel handle and round bar shaft for trouble free operation.
