sliding glass door handle. Markings on inside say "Keynetic" and "Imperial" don't see any numbers.

the door handle is polished brass, with inscriptions on the inside: :Keynetic & Imperial. Door is 1.75 thick, and screws are approximately 4" on center (probably 3 15/16). latch is 12" in height. One of the screws is striped and won't tighten. Don't need mortise lock set. Current handle locks fine.

We don't sell this exact style handle set, but I believe our 82-087 will work just fine for you. It also has a 3-15/16" hole spacing and should be fully compatible with your existing mortise.
