12 ft mirrored closet (wardrobe) track 3 doors 48 x 96

Thanks for posting. This looks a closet track with raised rails, for rollers that have concave wheels. Is that correct? If so, see our 71" 23-272. Review the end profile below to confirm it could work for your setup. I am afraid we don't carry a 12' variant of this track, however you could adjoin two of the 23-272 tracks together to effectively get the same length. Take a look and let me know what you think.
