I have a 8 foot slider which due to bad wheels has damaged and torn up the existing track cover which was made of a dark plastic type material. I now have a bare metal threshold in good condition. Does your replacement track 80-105 go on the existing remaining threshold or was it designed to fit over the track with the old plastic cover. Thanks

The 80-105 is actually the track, not a cover. What you would do is remove your existing damaged track, line up the 80-105 with the door, and screw down into the remaining threshold. See 80-103 and 80-100 if you want a track cover.

I have a double sliding glass patio door that's is about 50 years old and the bottom track (threshold) is damaged in places and door jumps off track. Do you have a replacement track I can purchase. Track is 5 foot long and 4 inch wide. It has two raised rails that measures from edge 7/8" and 2-1/2" or from other side 1-1/2" and 3-1/8". Pictures attached

Hey, Keith. Looking at your photos, I believe the best solution would be to use the taller track cover, our 80-100. I believe you have the height for it, but just in case you should check the dimensions to make sure. Use a short screw like the 33-071 on each end to keep it in place. I would also check your rollers in the door as they could be worn and causing the damage to the track. Also, check the video below.
