PGT Tandem Patio Door Roller 900-22693-NPB
[900-22693-NPB]

This was not my first purchase from WindowDoorParts.us and probably won't be the last. They answer the phone every time and help you find the exact part needed. Pricing is another plus with quick shipping a given. The only draw back is that I might have to put a warning sticker on the extra heavy patio doorwall, that the tandem nylon rollers and track topper went on, because you literally need only one finger to open them. Would be hard to imagine doing it without your help, thank you.
