I'm not sure who built these sliding doors. If you already have sliders in your home and want matching screens, it would be best to call the manufacturer of your sliders. Otherwise, an easier fix, due to trying to integrate different bottom track designs, would be to contact a retractable screen company. There are a couple choices that can span up to 20 feet wide openings.
We build impact rated liftslide patio doors with a flush track and screens, if you are looking for the complete package.
