You’re full of deviousness, aren’t you? LOL :-)
That’s where the cross bar lock that pins into the saddle and header cone into action. But who’s going to pay for that?
I lived in Paris for a few months and my apartment door was this gigantic monstrosity, at least 2-1/2 inches thick with these edge pins, a bolt, a rim lock and vertical and horizontal crossbar locks. The damn thing didn’t even have a regular knob or latch. Just push to open after opening that maze of locks. I never saw anything like it before or after. And of course, the crossbar locks were keyed in the center of the door so even breaking through the wall you couldn’t reach the thumb turn to unlock it. I don’t think a police battering ram could knock that door down. A drug dealer must have lived there before. Crazy.
