What is a central locking bar on a vertical file cabinet?

A central locking bar is a vertical steel rod running behind all drawer faces, actuated by a single cam lock on the top drawer. When locked, the bar prevents all drawers from opening simultaneously with a single key turn. This is significantly more convenient and secure than individual drawer locks. At OfficeFurniture2go.com, central locking bars are standard on all commercial file cabinet configurations — call 1-800-460-0858.
