Patio door handle with keys
I am not sure the 82-086 legacy keyed handle set would work on your door based of off the measurements you have provided. Take a look at the diagram below of the 82-086 to see if this could work. If not, get back to us with the distance between the screw holes as well as the thickness of the door, and we will continue to search for other alternatives.
These handles are small.the handles have to be 12 " long. I drew a diagram of the door.
I found out the door is a Pella 350 series.
Thanks for getting back to us. If this is a Pella door, then you'll have to go back to Pella for assistance. We are not able to supply hardware for their sliding glass patio doors. It makes sense since we couldn't find anything based on your dimensions, either. I am sorry that we cannot be of more help.
The 82-402 might work, but you will have to do some adapting.
You can try this or go back to Pella for further assistance.
