10ft Sliding door track

Hey there, Saul. We don't sell 10' tracks, but you could use two of our shorter tracks and simply butt them together. I recommend our  80-106. This is 6' long, so you'll have to cut the excess off with a hacksaw. Otherwise they should work well as long as there's no gap between them. You can see the video below for more detailed instructions.

I'm told by my colleague that you also wanted to know who made your door, but I'm afraid that I don't know. Your door appears to use generic hardware so nothing really sticks out as unique to any one brand. That aside, I'm confident that my recommendation will work.
