Anderson sliding patio door hardware

Hello! I'd be happy to help you replace these parts, but I'm not sure what you have. I will need you to take some preliminary photos of the handles in question so I can see if anything in our inventory matches. Please note that I may need more photos and information after that, but I need to know what to ask for, first. 

Thanks for reaching out. Andersen no longer makes this old style handle set, unfortunately, but the good news is that the modern iteration works just as well on the same door. See our 88-013 interior handle and 88-014 exterior handle. These are sold separately. We also have the 88-019 interior and 88-020 exterior, which serve the same function but have a different design.
