Depending on the year, bomar didn't make all of the port lights. On my 2008, which was built in 2007, Bomar made the hatch but Jim Black made the port lights. If they are made by Jim Black, his signature logo should be on the window somewhere. It is etched into the glass. Great Lakes Skipper is a dealer for them.
Isn't there a plastic bead that comes out so you can just put in new mosquito screening and fasten it with the beading? That's how my port light screen works. Not sure about the portals.
MyDream, I just re-screened my port screens this year. I don't know if they are similar to mine. On mine, there is a rubber gasket once you open the window, and under the gasket is a plastic oval ring which the screen is glued to and is removable. I bought fiberglass screen from Home Depot, some spray adhesive and it became a DIY project that was very easy, and cheap to do. Hope this helps!
