Looking to replace my old sliding mirrored closet door

Hello!

Thank you for waiting during this busy season of ours. This looks like a track for convex roller wheels like the 23-240, 23-241, and 23-242. Our tracks aren't as wide as yours, however. Take a look at the specifications for these parts and see if you think they could work for you. 

Unfortunately, we do not sell replacement closet doors. I am sorry for any inconvenience.
