How much does a 2-drawer fireproof cabinet actually hold?

Plan for roughly 50–60 lbs of hanging folders per drawer for a standard letter-size 2-drawer fireproof cabinet — the usable interior is smaller than you'd expect because the fire-insulating wall (typically 3"–4" thick on each side) eats into the interior volume significantly compared to a standard cabinet of the same exterior dimensions. Lateral fireproof models offer more usable drawer space for the same footprint.
