Hello,
Thanks for posting! We do not have an exact match for your closet door bottom guide but we do have two replacement options worth considering. Take a look at our 23-215 Bypass Bottom Guide Assembly and our 23-081 Mirror Wardrobe Door Roller; both of these have been recommended to replace this in the past but we have not received confirmation on which of them worked the best.
Carefully compare their dimensions and design to your existing guide to determine if either of these could work for your repairs.
This guide and roller are both compatible with our convex style tracks; they are 48" 23-240, 60" 23-241, and 72" 23-242 Sliding Mirror Door Bottom Tracks. You'll need to look over the dimensions below to see if it would be a fit for your door.
