White plastic inspection port with a 4" (100mm) opening. These opening ports are useful for sealing off compartments in sailing dinghies and other vessels while still allowing access. This is a two-part item consisting of a screw lid and a flange unit. The flange has six countersunk fixing holes to take 8-gauge screws. Six concentric ridges on the underside of the flange allow a fully waterproof seal when installed with a suitable marine silicon or mastic.
Nairn inspection ports are manufactured to high tolerances using premium ABS plastic materials to provide high strength, durability and watertightness even in the most demanding applications.
Note that screws for installation are not included.
