UPDATE: Lewmar no longer makes this part. We have sold the last that Lewmar made. They are no longer available.
Replacement white plastic interior trim ring for original Lewmar aluminum framed opening portlights. To help you identify this port, the lens measure 5" X 12" and has no frame surrounding the lens itself. The ports secure closed with two dogs which rotate open and closed like turning a key in a lock.
They were used on several Catalina models in the quantities listed: (2 ea) on the Capri 26, Catalina 270, Catalina 27, Catalina 28, Catalina 37 and Catalina 42; (4 ea) on the Catalina 30 and Catalina 38; (7 ea) on the Catalina 320; (8 ea) on the Catalina 34; (6 ea) on the Catalina 36.
Although the dates these portlights were used by Catalina on each model were not recorded, we do know that Lewmar produced them from 1982 through 1988.
Using the Catalina 30 as an example: Don't assume your 1982 Catalina 30 uses these portlights. Catalina might have had a different brand of portlight on the shelf which they used until their supply was exhausted at a later date.
