Patio Sliding/Gliding Door 2 Point Mortise Lock PM526A-WHITE

The big box stores don't carry this kind of lock, very glad to have found it here. This appears to be the exact same lock as what came off of my five year old sliding glass door. Performs a little quieter than the previous lock, and the mechanism is 'tighter' too, feels more precise. It was a perfect fit. And, this lock as the pin that won't allow the door to be locked without being closed, which my old lock did not. I used the old screws since the new ones were a larger diameter and I did not want to drill the holes bigger. Shipping was faster than advertised. Hope the seller still has these in another five years.

Fit perfect. Looks and operates.great. Shipping was actually better than advertised.
