  1. And here is why. The average locking mechanism has a certan volume that can not be manipulated in any other way but redesigning/reengineering it. So if the concave lock is used the door would have to be considerably thicker.
    And sudenly the price of one lock is no longer economic.
    This ofcourse doesn't apply to specials like the anti burgular doors wich are already very thick.
