Well now I officially have an installed screen door. I'm sure not many deuces have one. I was not sure what I wanted to do, either get one custom made, make one out of wood, cut down a conventional screen door, or cut down a sliding door screen panel. The latter won out. Took it apart, shortened and narrowed it, rescreened it, reinforced it and installed a mesh shield on the lower portion. Squeezed in a regular door handle and latch. Installed backwards as the door opens inward. Some weather stripping and a threshold and it's done. Works well with the fold up ladder too. Doubt much gets done tomorrow as we have some weather moving in.
