Masterpiece patio door, about 20 years old.

A home owner from Scottsdale says:
Looking for a dual hook mortise lock. The screw holes for the door are about 9 3/4 inches from center to center. The gap on the receiver end is about 5 5/8 inches. Hole in the door is about 3/5 inch wide and 9 1/4 inches high.

Thanks for your patience. My first choice would be our 82-239 mortise latch. Take a look and see if it matches up to your dimensions. I am not sure if you can use your existing keeper in the side jamb. You may also need our 82-249 keeper. Please review this and get back to us with some thoughts.
