A panic bar (sometimes called a crash bar or a push bar) is a door locking device consisting of a spring-loaded metal bar fixed horizontally on the inside of an exit door roughly 40 inches up from the bottom of the door. When the panic bar is pushed, the latch releases and the door opens outward.24 hour locksmith las vegas This mechanism allows for a door to be opened quickly and easily when a panicked crowd presses against it in an emergency situation.
