UL 1-Hour Class 350 fire file with a concealed safe
Built for offices and records managers who need fire protection plus a hidden safe, the FireKing Safe-in-a-File (3-2131-CAWSF) is a three-drawer legal-size cabinet with a concealed safe behind a false top-drawer panel. It carries a UL 1-Hour Class 350 fire-with-impact rating tested to 1700°F, a 2000°F explosion test, and a 30-foot drop, plus an ETL 1/2-hour media rating. Made in the USA.
This three-drawer unit measures 40 1/4 inches high, 20 13/16 inches wide, and 31 9/16 inches deep, and weighs 604 pounds. Each legal-width drawer offers a 26-inch deep, 15 1/4-inch wide, 10 3/8-inch high opening sized for hanging folders, giving a full office of file storage plus the discreet integrated safe compartment up top.
Engineering & Security
- Concealed safe-in-a-file: A false top-drawer panel hides an integrated safe compartment, adding a discreet security layer above standard filing for cash, jewelry, or small valuables.
- Medeco high-security key lock: UL-listed Medeco high-security key locks guard against unauthorized access and key duplication on the cabinet's secured compartment.
- 14-gauge welded steel wire lattice: Insulation is encased in a lattice of 14-gauge galvanized welded steel wire, reinforcing the body against fire, impact, and explosion.
- Insulated individual drawers: Each drawer functions as a separate insulated container, so contents stay protected drawer by drawer rather than relying on one shared cavity.
- Field-replaceable steel panels: Damaged exterior panels can be swapped individually, restoring appearance and integrity without replacing the entire cabinet.
- 604-pound build: At 604 pounds the three-drawer cabinet resists casual relocation while remaining a standard 20 13/16-inch wide office footprint.
Fire Protection & Interior
- UL 1-Hour Class 350 fire-with-impact: Underwriters Laboratories certifies one hour of fire protection keeping interior under 350°F, tested at 1700°F exterior exposure for paper records.
- Impact and explosion tested: UL testing includes a 2000°F explosion test and a 30-foot drop, verifying the cabinet survives structural collapse during a fire.
- ETL 1/2-hour media rating: The file drawer carries an ETL 1/2-hour rating for digital media, protecting drives and tapes that fail at lower temperatures than paper.
- ETL-verified water resistance: The cabinet is ETL verified against water from sprinklers and fire hoses, helping keep documents and media dry during fire response.
- 100% gypsum insulation: Gypsum-based insulation releases moisture under heat to hold interior temperatures down through the rated fire exposure.
Drawer Layout & File Capacity
- Three legal-size drawers: Three full-depth drawers accept legal-width hanging folders, suiting active business filing alongside the concealed safe compartment.
- 26-inch deep drawer opening: Each drawer opens to 26 inches deep, 15 1/4 inches wide, and 10 3/8 inches high for high-capacity hanging-folder storage.
- Maintenance-free suspensions: Drawer suspensions run maintenance-free with surface-mounted pulls that add insulation while keeping daily access smooth.
Ideal Buyer & Use Cases
The 3-2131-CAWSF suits law offices, medical practices, and businesses that must keep legal-size records fire-safe while discreetly securing cash or valuables in the concealed top-drawer safe. At 40 1/4 inches high, 20 13/16 inches wide, 31 9/16 inches deep, and 604 pounds, it fits a standard office footprint.
Need less filing space? The two-drawer 2-2131-CAWSF is a smaller alternative. For more capacity, step up to the four-drawer 4-2131-CAWSF, which adds a fourth legal-size drawer in the same width and depth.
