The sizes range from 4 inches to 8.4 inches, with outside diameters ranging from 138 mm to 285 mm and inside diameters from 96 mm to 246 mm. The materials used are primarily PP (Polypropylene) and ABS (Acrylonitrile Butadiene Styrene), which are anti-aging and ultraviolet resistant.

Features & Benefits:
The hatches are designed for both vertical and horizontal applications and feature a heavy-duty lid with a non-slip surface. They include a durable water-resistant EVA seal and a hidden fastener design. The white hatches are made of PP, while the black ones are made of ABS. These materials ensure the hatches are engineered to withstand tough marine elements and do not turn yellow over time. The design allows for easy access without the need for tools.

Additional Features:
Some models come with a removable bag for storage. The hatches are available in both Kraft Box and Color Box packaging options.

Applications:
These hatches are suitable for marine environments due to their corrosion-free synthetic fittings and durable rubber seals. They are designed to open 180 degrees for easy access.
