UL 1-Hour fire-rated lateral filing for legal and letter records
Built for offices that must safeguard active paper records, the FireKing Classic High Security Lateral 3-4422-C is a three-drawer 44-inch-wide lateral file cabinet carrying a UL 1-Hour fire rating that holds interior temperatures under 350 degrees during a 1700-degree exterior test. It ships with a UL-listed Medeco high-security key lock and is made in the USA.
This three-drawer cabinet measures 44.5 inches wide, 40.25 inches high, and 22.13 inches deep, and weighs 751 pounds. Each drawer offers a 38.94-inch-wide, 15.13-inch-deep, 10.75-inch-high interior sized to hang letter and legal files side to side, giving departments substantial fire-protected capacity within a standard lateral footprint.
Engineering & Security
- UL-listed Medeco high-security key lock: One pick-resistant Medeco key lock secures all three drawers, with a bypass option to leave selected drawers accessible during the workday.
- Multiple lock upgrades: Optional dial combination, Group 1R manipulation-proof dial, or UL-listed electronic lock can replace the standard key lock to match your security policy.
- UL 30-foot impact rating: Independent UL testing confirms the cabinet survives a 30-foot drop, protecting contents if a floor collapses during a fire.
- Three-drawer lateral design: Replaceable drawer components let you repair only the damaged part rather than the whole cabinet after an incident.
- Made in the USA: FireKing builds this Classic High Security Lateral series domestically, supporting consistent quality and parts availability.
Fire Protection & Interior
- UL 1-Hour 350-degree fire rating: Tested at a 1700-degree exterior temperature, the cabinet keeps its interior below 350 degrees for one hour to protect paper documents.
- ETL 1/2-Hour digital media rating: An additional ETL listing covers a half-hour of protection for digital media, which fails at lower temperatures than paper.
- Water and sprinkler resistance: The design also limits damage from building sprinklers and fire-hose contact that typically accompany a fire event.
- Letter and legal filing: Each 38.94-inch-wide drawer hangs letter and legal files side to side, with cross hangers available for letter-size side-to-side filing.
Ideal Buyer & Use Cases
This 44.5-inch-wide, 40.25-inch-high, 22.13-inch-deep cabinet weighing 751 pounds suits law firms, medical offices, and records departments that need fire-protected lateral storage for high-volume legal and letter files.
If three drawers exceed your needs, the two-drawer 2-4422-C is a smaller alternative; offices needing more capacity can step up to the four-drawer 4-4422-C, while the narrower 3-3822-C and 3-3122-C suit tighter footprints.
