Door handle
Thanks for writing in! I am confident that we can supply you with the replacement handle set needed for your door. However, I'll need to see a photo of the handle set to confirm the right fit. We have a few different handle sets compatible with our 82-265 Multi-Point Mortise Lock.
Please let me know if you have any questions in the meantime.
Thanks for the photos. Your patio door handle set looks a lot like our 82-086 Legacy Keyed Handle Set. To confirm that this is the right replacement be sure to double check the dimensions and design of the part. Although, I am confident this is the replacement handle set you'll need.
