What is an anti-tip mechanism on a vertical file cabinet?

An anti-tip mechanism is an interlock system that prevents more than one drawer from being fully opened at the same time, preventing the cabinet from tipping forward under the weight of open drawers. This is a mandatory safety feature on any commercial file cabinet. Cabinets without anti-tip mechanisms pose serious tip-over injury risks. At OfficeFurniture2go.com, all file cabinets include anti-tip interlock — call 1-800-460-0858 to confirm on any specific model.
