Vinyl bottom track of screen door has buckled
My sliding glass door has what appears to be a vinyl bottom track for the screen door, and it has buckled (perhaps due to unusually hot temperatures recently) so that the screen doors cannot be slid in their track.
Does anyone know what brand of door this is, or where I can obtain a replacement bottom track? I can find no identifying marks on the door, so I'm hoping that the track itself is distinctive enough to identify the manufacturer. The track can be pulled out without tools. If a replacement is hard to find, I was thinking of taking it out and trying to use a heat gun to soften it, and then clamping it around a piece of wood that would fit inside it (the track is U-shaped, in an attempt to remold it to its original shape.
