Door jambs
A door jamb is the vertical portion of the frame onto which a door is secured. Most types of door fasteners and deadbolts extend into a recess in the door jamb when engaged, making the strength of the door jambs vitally important to the overall security of the door.
In closets, it is possible to incorporate an electrical trigger in or on the jamb, controlling a light fixture in the closet so it turns on when the door is open, similar to the device found in a refrigerator.
The word "jamb" comes from the French "jambe", meaning "leg".[1]
Door anti battering ram pin
Drill a 5/8 hole 6" deep in your floor if concrete and about 6-8" back from your door. Put a pin in it at night. When someone uses a foot or battering ram to knock the door in, the door will bust the lock and open till it hits the pin in the floor. Energy has dissipated and the door will not open any further. Its a small enough opening no one can squeeze through, so they will have to hit the door again, probably a couple of time to get in. That gives you time to react. Just be careful at night you don't kick the pin with your bare feet.
(Door) box strike plate
A metal plate on a door frame into which the bolt of a door lock projects, and which provides a complete housing that protects the bolt opening from tampering.
