I found Swisco by googling "sliding screen door track lower". I have three 6' patio doors of unknown provenance which use the standard el cheapo sliding screen doors available at any home center. The lower track has worn out on a couple of them and it doesn't seem to be so readily available. The attached pic shows that the original was a piece of flat metal stock with a hard plastic(vinyl?) ridge piece attached which accommodates the rollers on the bottom of the screen. It's less than a half inch tall and about a half inch wide. Can one of your parts be used to replace this?
Thanks so much,
Joel
