A training device is described for perfecting the art of forcibly opening a door in an emergency. The training device has a frame and a door placed in the frame. A dead bolt is mounted in the door and protrudes from the door in a locked position relative to the frame. A vise is attached to the frame. The vise has a movable jaw mounted on a block and a stationary jaw, and means for tightening the movable jaw against the dead bolt. The dead bolt protrudes from the door between the stationary and movable jaw. A method of using the training device causes the door to pivot and the dead bolt to move off of the vise, thus simulating an actual forced opening.
