Sliding Glass Door Handle with lock

I believe your door could be an older style Daryl patio door from the 1960's. Due to its age, I don't believe your exact handle is still available. I would suggest using the 82-005 surface mounted patio handle. It just mounts right to the face of the door with screws, for which you would need to drill new holes. If you want an outside keyed handle, consider our 82-306.
