Sliding mirror door roller

A handy person from California says:
Hi,

The bottom mirror sliding door roller has a patent number on it 4850145 THM. I would appreciate your help to identify the part number. I am looking to replace these rollers on my sliding mirror doors.

Thank you,

Alfonso

Hey Alfonso. This exact roller isn't made anymore, but check out our 23-064. Look over the dimensions and see if you think this could work for you.
