I saw you answered. I want to talk and discuss with u before I order. I saw a video where one bottom or top pin 21-007 can be snap to lock into the slots on a door. I like that and can hold the position to proper place IF IT WORKS FOR MY DOOR AND I HAVE SLOTS FOR THE SCREW WITH NOB SLIDES IN TO THAT HOLE . My hole on a door is not a square it is rectangle.
Can we use that instead. Please look all photos and guide me so I can buy.
