I replace my companionway hatchboard with Lexan that I bought on eBay.
Did the cutting and machining myself. It was easy to work with. This
is who I bought it from:

How thick are your companionway slides? I don't see anything listed over
about 1/3 inch. I'd like to do something similar but my last boat had
1/2 inch and my current boat has 3/4 inch sliders.
