When you are protecting valuable documents you want the best. When it comes to fire protection, half as good is no good. Fireking is the choice among many companies for its outstanding, dependable fireproof filing cabinets. The Patriot will withstand a 1700-degree fire for a minimum of one hour protecting stored documents. Protecting against the heat is half the battle, fires very commonly result in building or structural collapse – an impact-rated file must be able to withstand a fall from multiple stories. For a UL-listed safe to be labeled “Impact Rated,” it is heated to 1,550 degrees Fahrenheit in a furnace, raised three stories and dropped onto a pile of bricks, and then returned to the furnace and reheated. To meet the listing requirement, temperatures inside can't have risen above 350 degrees Fahrenheit, and sample papers left inside must be readable. The Fireking Patriot file cabinets meet this stringent standard. If the file cabinet does endure a fire, Fireking offers lifetime file cabinet replacement.
