If your wheel is concave, then our 23-086 mirror door roller can be used in its place. Check it out and see what you think. 

A quick learner from USA says:
how is this different from Product Code: 23-070? does it perform differently?

The 23-086 has a ball bearing wheel while the 23-070 does not. I'm personally of the opinion that ball bearing wheels operate much better than the alternative.
