How heavy are fireproof filing cabinets compared to regular ones?

Significantly heavier — the double-wall insulation that makes them fireproof adds substantial mass. A 2-drawer letter-size fireproof cabinet typically runs 150–250 lbs; a 4-drawer vertical can reach 300–500 lbs; a 4-drawer lateral can hit 400–600 lbs. That weight has real implications for delivery logistics, floor loading, and installation, especially on upper floors. Plan for freight delivery and professional placement on large units.
