Pre-701 Pella Roller Assembly

A home owner from Halifax, Nova Scotia says:
Hello; I have what appears to be the same unit as pictured on your site as "Pre-701" (Pella). The dimensions on the assembly are similar, but the height of the unit is 2", not the 1 11/16" as the 701. There are no dimensions given for the wheel itself, but mine is 1 1/2" diameter,3/8" width and with a 3/8" shaft. Actually, all I really need are replacement wheels, but the other responses appear to indicate that these (or replacements) are not available. Are there "Pre-701" units available, and if not, what are your suggestions regarding suitable replacements?

Paul Sr. from SWISCO responded:
The 81-098 replacement Pella patio glass door roller will replace both the "Pre-701" and the "701" Pella models. The wheel has a 1-1/2" diameter and a 3/8" thickness.
A handy person from Westminster, Colorado says:
My Pella sliding glass patio door was installed in the late 1980s. Is it too old to be a "Contemporary" sliding door, i.e., will these rollers fit a 20+ year-old Pella sliding glass door?

The 81-098 replacement roller is used on Pella sliders up to approximately 1992. To find the proper replacement roller you are going to need to remove the roller from the frame and match it up the product pictures of the various replacement patio glass door rollers. If you need help identifying the proper replacement, reply to this discussion with photos of your patio door roller.
