Searching for Atrium Series 332 sliding glass door replacement handle

Thanks for posting. The mortise lock looks like our 82-265, which has two latches that curve inward. Please confirm this is the case with your lock as well. If so, a handle set with 3-15/16" hole spacing like our 82-030 should work for your door. Let me know if you have any other questions.
