The 81-098 Pella rollers worked like a charm!

Our pella sliding glass door was very difficult to open and close. Went with the 81-098 original rollers after reading a few posts. Our order was in the mail within an hour and on our doorsteps the next day. Followed this sites directions for installation and our door slides like a charm. Don't be afraid to spend the extra for original parts. Four stars for swisco!
