weatherstrip for Pella sliding patio doors

Hello,

Unfortunately, we do not carry an exact match for your weatherstripping. The closest option that we carry would be the 58-055 offset bubble seal but it doesn't have the extra flange shown in your photos. Take a look and review the specifications below to see if this could be adapted to work for your repair. Is not, your best bet would be to reach out to Pella directly. Thank you!
