A Birmingham bar is a metal bar or strip fixed to the hinge side of a wooden door frame to help protect it from forced entry. It belongs to the family of door strike reinforcers and contributes to physical security.
Door strike reinforcers significantly enhance the security of a door, as they make it much more difficult to use brute force to open the door.
A metal strip fixed to the locking side of the door frame for reinforcing purposes is called a London bar.
