Hello! By your sticker, I can see that you have an Acorn Series 1200 door. This used our 81-030 tandem roller, though the only way to confirm is to remove your existing roller and compare it to our specs. See how well they match.

Unfortunately, the given information is not enough to verify what door you have. As Paul stated above, there is a chance you might have the  81-030 tandem roller, but this is far from a guarantee. The only way to properly identify a patio glass door roller is to remove the original for reference. There is unfortunately no easier way; it's going to be an involved project any way you look at it.
