roller with 1/8" offset for custom pocket door

Thanks for posting. Unfortunately, it would be hard to recommend a replacement roller for a custom pocket door. It's difficult to say what would work best, especially when your original roller did not work well to begin with. That said, please take a look at our 23-009 Front Closet Door Roller. It has a 3/4" wheel and a 1/4" offset. Do you think this might work for you?

As for a 1/8" offset with a 3/4" wheel, I don't see any that would particularly match your original roller. That said, please look through our Sliding Door Rollers catalogue to see if there is anything you think might work for you.
