I'm afraid I don't have a record of tandem rollers used on this door. It's sometimes associated with our 81-289, but this is a single wheel assembly. The only way I can determine what you have at this juncture is to see the original removed from the door. This is typically always necessary regardless of the patio door in use and is the only way to reliable guarantee a match. Even using the series of the door and manufacturer as a reference can only give you an educated guess, at best. |
