They don't. You can't put conventional screen doors on the "French doors"
you've described. I've seen an ad for an indoor screen that operates like
roll-up window shade except that it's installed horizontally, and slides
across the door opening to provide screening, but I haven't been able to
find it in stores. We solved the problem by just adding a large screen room
over our deck so that you go through the french doors to an outside,
screened-in deck, but that's a solution that's probably most suitable only
for Florida. Regards --
