sliding glass door handle

Thanks for posting. This handle set reminds me of the 82-003, which has 3-15/16" hole spacing. It also has a similar lever in the center as to yours. The only other thing to consider is whatever latch or lock inside the door that this handle set interfaces with to close the door. If you could open the door and show me a clear picture of whatever mortise lock is inside it, that should determine if the 82-003 is indeed what you seek. 

The latch the 82-003 has indeed looks similar to what you show here. If the specifications for this part match up with yours then you should be good to go.
