Screw-on inspection hatch, white colour. Diameter of opening 152mm, external 210mm and cutting 163mm. EVAL inspection hatches are made of UV-resistant ABS plastic. So they can also be used outdoors. They have a removable lid and, thanks to the special thread, they open very easily and can be automatically removed by turning 900 to the left. This makes it easy to access and work in various areas of the boat. The screw locations of the EVAL inspection hatches are covered and the hatches also include a seal, to ensure a perfect seal.
