Sliding glass door handle

Hello there. I'm afraid I can't cross-reference that Simonton code to any handle set in our database. If your old handle set has a hole spacing of 3-15/16", and if the thumb latch and key lock are offset toward the lower screw hole, rather than perfectly centered between them, then there's a good shot the 82-086 will work for you. But if in doubt, send us pictures of your existing handle set along with the mortise lock in the door that it interacts with, and we should be able to confirm for you.
