Thanks for posting. We carry one type of sliding glass door track, our 6' 80-106. Take a look and review the video below to see if you think this setup could work for you. To reach 8', you would need to purchase two of these tracks, adjoin them, and then cut off the excess length with a hacksaw like our 75-023A. Let us know if you have further questions.
