Mirror closet door track

Thanks for writing in. It looks like this track has raised rails for concave rollers, or rollers with wheels that have grooved edges. Is that so? If so, our 23-270, 23-271 or 23-272 style tracks are our best match. The exact design may be different, but so long as the distance between the rails matches what is shown below, I think this style could work for you. Take a look and see what you think.
