Lower rail of Stanley closet glass double door sliding mirror 72"

Hello, thank you for posting,

We should be able to assist with a new track, but to further review, are you able to provide a clearer image of the wheel? Or confirm if it is a convex or concave wheel style? From there we can determine which style track you need. Thank you! 

Thank you,

Your closet doors use convex wheels. Please review the 23-242 bottom door track. Compare the dimensions below to confirm a good fit! Let us know what you think and if you have any additional questions!
