We have a Anderson sliding door that needs new bottom rollers but can figure out how to get the old ones out. It looks like they snap in they measure wheel is 11/4" outside measurement is 33/4"

It's possible you could have the 81-128 Andersen glass door roller. Carefully compare it to your own hardware to confirm that they match.
