This old-style Pella replacement roller will fit in Pella doors made before 1996. The roller is "pressed fit" into the door; it does not use screws to hold it in place. This roller does not have flanges like the roller for the newer Pella doors. If you have a newer Pella door (after 1996), search for P-4998-FLR.
