Can I use all drawers of a vertical file cabinet simultaneously without tipping concerns?

No — you should never open multiple drawers of a vertical file cabinet simultaneously. The anti-tip mechanism on commercial filing cabinets prevents only one drawer from opening at a time — when one drawer is open, a locking bar prevents other drawers from opening. This is a critical safety feature: the weight of an open, loaded drawer shifts the cabinet's center of gravity significantly forward, and opening a second drawer simultaneously could cause the cabinet to tip forward. Never disable or bypass the anti-tip interlock. If your cabinet's interlock isn't functioning (you can open multiple drawers at once), it needs service or replacement.
