locking file storage boxes

Listings show keypad and combination/password locks; some models include an emergency key or override. Simpler boxes often use a latch designed to accept a small padlock for added security.

Materials vary by model: heavy-gauge steel (common for drop/floor safes), silicone-coated fiberglass (used in fireproof file bags), polyester fabric (for soft cases), plastic (typically polypropylene) storage bins, and paperboard boxes.

Many boxes are sized for standard documents—most listings explicitly mention compatibility with letter-size (8.5 × 11 in). Larger or double-layer organizers also note they can fit legal-size files.

Smaller document organizers are designed to be portable—often collapsible or fitted with sturdy handles for easy carrying. Heavy-duty steel drop/floor safes are much less portable; for example, one listing shows an item weight of 82.95 pounds and includes mounting options.

Some models are designed for secure stacking (grooved or indexed lids), while others are collapsible or include a rigid inner frame so they fold or stack neatly when not in use.

Sample external dimensions listed for plastic and paperboard file boxes include 15 × 10 7/8 × 11 1/2 in; 10.5 × 12.8 × 16.3 in; and 10.75 × 14.13 × 18.13 in.
