Looking for closet track

Thanks for posting. It's a bit tough to tell from this angle, but I believe this is a track with 'raised' rails for concave wheels. If so, then see our 23-270, 23-271 or 23-272 Tracks for Concave Rollers. If the distance between the rails, as shown below, matches what you have, then I think this can work for you. Take a look and let us know what you think.
