VERIFIED PROTECTION RATINGS:


UL 1-Hour Class 350 fire protection for legal records
Built for offices that store irreplaceable legal files, the FireKing 4-2125-C from the 25-deep High-Security Vertical series carries a UL 1-Hour Class 350 fire rating, holding interior temperature below 350°F through a 1700°F furnace test. It is also UL 30-foot impact-rated, ships with a Medeco high-security key lock, and is made in the USA.
This four-drawer vertical cabinet measures 52.75 inches tall, 20.81 inches wide and 25.06 inches deep, weighing 521 pounds. Each legal-width drawer offers roughly 10.38 by 15.25 by 19.75 inches of interior space for about one cubic foot of hanging files per drawer, giving a full department lateral filing capacity in a single insulated footprint.
Engineering & Security
- Medeco high-security key lock: Ships standard with a UL-listed Medeco key lock that resists picking and drilling; an electronic or combination lock is available as an upgrade.
- UL 30-foot impact rating: Verified to survive a loaded fall through a burning floor without bursting open, protecting contents if a building collapses during a fire.
- 521-pound steel build: Heavy welded-steel construction and the cabinet's mass deter casual removal and add stability under daily four-drawer use.
- Made in the USA: Manufactured by FireKing in the United States, supporting consistent quality control and parts availability over the cabinet's service life.
- Not burglary-rated by design: This is a fire-protection file cabinet, not a burglary safe, so pair it with a rated safe for cash or high-value valuables.
Fire Protection & Interior
- UL 1-Hour Class 350 rating: Independently tested to keep interior temperature under 350°F for one hour, the threshold that protects paper documents from charring.
- 1700°F furnace test: Withstands an external furnace temperature of 1700°F during the rated hour, reflecting the heat of a structural fire.
- Asbestos-free dry insulation: Each drawer is a separately insulated container, so closed drawers maintain the fire seal independently of one another.
- Legal-size drawer interior: Interior of about 10.38 by 15.25 by 19.75 inches per drawer holds hanging legal folders, roughly one cubic foot of files each.
Drawer Layout & File Capacity
- Four legal-width drawers: Provides four full vertical drawers sized for legal documents, suiting law offices, accounting and records departments with heavy active filing.
- Independent insulated drawers: Because each drawer is its own insulated chamber, you can keep some drawers open while others retain full fire protection.
- Vertical footprint: A 20.81-inch-wide, 52.75-inch-tall body stacks four drawers into a compact floor area for offices tight on space.
Ideal Buyer & Use Cases
The FireKing 4-2125-C suits law firms, accounting practices and corporate records rooms that need UL 1-Hour Class 350 fire protection for a large volume of active legal-size files. At 52.75 by 20.81 by 25.06 inches and 521 pounds, it delivers four full drawers of protected vertical filing in a single unit.
If you need less capacity, the two-drawer 2-2125-C (sku 2-2125-CAW) offers the same legal width and fire rating in a shorter body, while the four-drawer letter-width 4-1825-C (sku 4-1825-CAW) is a slightly narrower option; the Premium Designer 4-2125-C (sku 4-2125-CMA) matches this cabinet with upgraded finish.
