I acquired 70" wide by 80" high mirrored closet doors without the tracks but can't figure out what the upper track looks like. Can you help. I think I know which lower track to order but not the upper.

Many thanks for writing in. You can use our 23-246 Top Mirror Door Track. This accepts up to 1-1/2" wide top guides.
