BOMAR Flagship opening elliptical porthole model 618 is intended for installation in boat hulls and other marine bulkheads. The porthole has external dimensions of 209 × 468 mm and provides ventilation and visibility through an opening, smoke-colored acrylic lens.
Installation requires a cutout of 184 × 443 mm and fits a hull or bulkhead thickness of 6–35 mm. The hidden fastening means there are no visible screws on the exterior. A matching external trim ring is included and provides a finished edge around the mounting opening.
The white frame is made of nylon, while the fastening parts are made of 316L stainless steel. The beveled exterior and the molded drainage profile are designed to lead water away from the opening. The narrow frame construction also provides a large field of view.
The porthole is opened and closed with adjustable quick-locks. The included insect screen limits insect access when the porthole is open and can be used without blocking ventilation. The construction is CE-certified for marine installations.
