Replacement rollers
I'm afraid I don't. There's only one way to identify patio door rollers, and that's to see them removed and without obstruction.
This is going to be a pretty time and labor-intensive project. You need a clear afternoon and two pairs of hands to take the door down. That's just to identify; you'll need to do it again once you're ready to replace the rollers with the new ones.
I know that sounds like a hassle, but that's what's required for this project at minimum. There's no way out of it. Brace yourself for it now.
Once the full roller assembly is out, take a clear photo of the back end, top, and sides. You'll also want to take detailed dimensions and write them down in case there's more than one possible option. Very often it comes down to a minor difference in size. A photo of a tape measure is not sufficient; all measurements must be written and precise on your end.
Once we have that data, we can check our inventory for a match.
