What is a locking bar on a fireproof filing cabinet?

A locking bar is a vertical rod or bar mechanism on a filing cabinet that runs through all drawer locking points, controlled by a single lock at the top. When engaged, the locking bar locks all drawers simultaneously with a single key turn, rather than requiring individual locks on each drawer. This is the most common locking system on commercial vertical filing cabinets, including fireproof models. It's convenient (one key for all drawers), reliable (single mechanical system), and allows master-key systems for office-wide key management. Most quality commercial fireproof vertical cabinets use locking bar systems. Lateral fireproof cabinets may use a different system — call 888-719-4960 for locking system details on any model at FindOfficeFurniture.com.
