VERIFIED PROTECTION RATINGS:


One-hour fire rating with re-locker security for documents
Built for offices and homes that store irreplaceable paper, the FireKing KF3522-1WHE from the Fire File Cabinet Series pairs a tested one-hour fire rating with real burglary hardware. A multi-user electronic lock, an independent glass-plate re-locking device, and 1.26-inch three-way active bolts guard documents, cash, and media. It is made in the USA.
This is a substantial floor unit measuring 41.50 inches high by 28.00 inches wide by 29.00 inches deep and weighing 720 pounds. Inside, 35.50 by 22.00 by 21.25 inches yields 9.60 cubic feet, and two adjustable shelves organize binders, files, and small valuables across the full interior.
Engineering & Security
- Multi-user electronic lock: The digital lock supports multiple user codes and re-programming in about 30 seconds, suiting shared office or family access.
- 1.26-inch active bolts: Three-way active bolts seat into the frame to resist pry attacks across the door's locking edge.
- Independent glass-plate re-locker: A glass relocking device triggers if the safe is attacked, dropping a secondary lock to block forced entry.
- Stationary vertical locking bar: Heavy-duty locking bar guards the hinge side, so cutting the hinges does not open the door.
- Bolt-down kit included: An anchor hole and supplied kit let you fasten the 720-pound body to the floor against removal.
Fire Protection & Interior
- One-hour fire rating: Tested to a one-hour fire rating to shield documents, cash, and media during a structure fire.
- 9.60 cubic feet interior: Interior of 35.50 by 22.00 by 21.25 inches holds binders, folders, and boxed records with room to spare.
- Two adjustable shelves: Repositionable shelves separate files from valuables and adapt to tall or short contents.
- White finish, chrome handle: White exterior with a chrome tri-spoke handle fits office and residential settings without drawing attention.
Ideal Buyer & Use Cases
Choose the KF3522-1WHE if you need to protect paper records, backup media, and cash from both fire and theft in one cabinet. At 41.50 by 28.00 by 29.00 inches and 720 pounds with 9.60 cubic feet inside, it anchors permanently in a home office, practice, or small business.
If you need less capacity, the KF2722-1WHE and KF2715-1WHE step down in size and price; the KF5322-1WHE offers a larger one-hour-rated alternative when storage demands grow.
