I'm looking to replace the Johnson pocket door roller for a better grade without replacing the track!

This reminds me of our 23-136 Tricycle Hanger for Pocket Doors. Compare and see if you agree.

Interesting, but I'm looking for a replacement roller. I can't be the first person to have this request. Hasn't anyone made an improved roller for these pocket door tracks???

I believe the 23-136 would be our closest match. How do the dimensions align? Truth be told, pocket door hardware is actually very difficult to replace, as the new parts must be exact in dimension in design. We often end up recommending one of our track kits to replace everything entirely, but I do think the 23-136 might be your best bet. I can't say it's necessarily improved over the design of your first roller, but if it matches up I think it can work for you.
