Can't find any rollers like this anywhere

Many thanks for posting. That label unfortunately has to do with the glass manufacturer, not the door or rollers. We may be able to help, but I am pretty sure that this is just the internal portion of the roller assembly. There should be an outer housing still in the door. In order to ID a match, I need to see the whole thing together. If you can show us the whole roller, we'll do our best to narrow it down.
