no idea where to find this roller

A quick learner from Canada says:
On the side of the roller it says:

L Ricci-Tool
NC 514-643452C

See the photos for the measurements. I noticed in december of last year, somepne posted the same roller on this website.discussions/Rollers-for-Sliding-Patio-Door-77-62126 Was a replacement ever found?

I'm afraid your images didn't come through. If your roller matches the one in the discussion to which you linked, I'm afraid we never did find a match. Paul required further information but nobody ever got back to us.
