How does an anti-tilt suspension system work in a fireproof cabinet?

An anti-tilt suspension system uses an interlock mechanism — usually a bar or pivot system shared across all drawers — so that only one drawer can be pulled open at a time. When one drawer is open, all others are automatically locked closed. This prevents the cabinet from becoming top-heavy and tipping forward, which would be dangerous given the 300–500 lb weight of commercial fireproof cabinets. This is a required safety feature in all ANSI-compliant commercial filing cabinets. OfficeFurniture2go.com — call 1-800-460-0858.
