FireKing DS6420-2LG, 2 Hour Hour UL Rated Fireproof Data Media Safe

UL Impact Rating - The UL Impact Rating is equivalent to a fall from a three story building.
FireKing fireproof lateral filing cabinets carry the UL 350 1-hour fire rating. After a product has passed the Fire Endurance Test, another sample of the same product may be tested for fire and impact.

UL Explosion Rating
For this test, the sample is prepared in the same manner as for the two previous tests. The test furnace is left empty and heated to 2000F. The testers quickly open the door and insert the sample. For 30 minutes (20 minutes for units rated hour), the furnace is kept at 2000F. If no explosion takes place, the sample remains in the furnace until it cools sufficiently to handle.
