Promising Review:

“I just installed this lock on my Frenchwood patio door. It was super easy to do. I only had to enlarge one existing hole from 3/8 to 1/2 inch so the wire connector would fit through it. The instructions were clear, and it all works perfectly with the multipoint lock that we have on the door.” – Dundua, March 28, 2021, on Amazon.
