How does a full-height locking bar work on a vertical file cabinet?

A full-height locking bar is a steel rod running vertically inside the cabinet body. When the lock cylinder is turned, the bar engages notches on each drawer frame simultaneously, preventing all drawers from opening. Unlocking releases all drawers at once. This system is far more secure than individual drawer locks, as it cannot be bypassed by forcing a single drawer.
