Hi there, thanks for writing in. There are several factors to consider when identifying patio door rollers, and wheel diameter is just one of the them. We do carry other rollers with a 1" diameter wheel, so I don't advise basing your decision on that. Take a look at the video below for more details on the identification process, and feel free to upload some pictures if you need more assistance. |
