Patio door handle

I'm not so sure on this one. Your lock might be an older style Miller patio door lock. which should be able to use our 82-076 handle and 89-040 keeper. However, I'm not sure if the lock lines up with the cut out at the side of the door stile. 

Also, take a look at the 82-008 handle and 89-003 keeper. See if this one would line up better. Take note these handles are for 1" door thickness and are only 7-1/4" tall. Their dimensions might not fit yours. Let us know how it works out.
