Whitecap 4 in Opening Teak Porthole Trim Ring

The Whitecap teak trim ring provides a wood surround for a round porthole opening. It has a 4 in inner opening and a larger outer diameter for covering the adjacent surface. Teak offers a natural wood finish that can be matched to nearby cabin joinery.

The ring measures 6-3/8 in across and is 3/8 in thick. A 6 in inside-flange diameter and 1/8 in recessed back flange are also listed. Pre-drilled mounting holes simplify alignment with the intended installation. Because the outside and inside-flange dimensions differ, both surfaces need clearance.

Use the ring to finish the visible edge of a suitably sized porthole. Check the actual opening, flange clearance, and screw locations first. Its recessed back should be allowed for when measuring the surrounding panel. Explore more mounting and rigging hardware at CritPro.
