Swivel curved track single wheel rollers

Hello,

I do not believe that we would be able to supply your entire roller assembly since we do not carry anything designed to ride on a curved track like you've described. With that being said, we might be able to supply a new wheel if your housing is still in good shape. To confirm, we would need you to confirm the exact diameter of the wheel, as well as the type of door that the roller is from. Thank you!
