UL Class 350 1-Hour fire chest for legal-size records
Built for households and offices archiving legal-size paperwork, the FireKing SS104 SureSeal chest in the SureSeal series carries a UL Class 350 1-Hour fire rating that keeps interior temperatures low enough to protect paper and media. It is water-resistant to a submerged depth of one meter, secured by a key lock with two keys, and made in the USA.
At 7.3 inches high, 19.9 inches wide, and 17 inches deep, this 56-pound chest opens to a 14.8 by 3.8 by 12-inch interior sized for legal-size documents laid flat. The compact footprint and built-in handle let you store it on a shelf or grab it quickly during an evacuation.
Engineering & Security
- Key lock with two keys: A keyed lock with two included keys keeps the contents private without batteries or codes to manage.
- Dual compression latches: Two compression latches pull the lid down to form a tight seal against heat and water intrusion.
- Built-in carry handle: An integrated handle on the 56-pound chest makes it easy to reposition or carry out during an emergency.
- Made in the USA: Domestic manufacturing backs the SureSeal line with a 7-year warranty and a lifetime after-fire replacement guarantee.
- Not burglary-rated: This chest is a fire and water protection device by design and carries no UL burglary rating, so pair it with a secured location.
Fire Protection & Interior
- UL Class 350 1-Hour fire rating: The Class 350 listing means the interior stays below 350F for one hour of fire exposure, safe for paper documents.
- Water-resistant to 1 meter: FireKing rates the SS104 waterproof up to 100 hours submerged at a depth of one meter, guarding against floods and leaks.
- Legal-size interior: The 14.8 by 3.8 by 12-inch cavity holds legal-size documents flat alongside CDs, DVDs, flash drives, and portable hard drives.
- Media protection: Class 350 protection suits both paper records and digital media that degrade well below the survival threshold of plain paper.
Ideal Buyer & Use Cases
Choose the SS104 if you need a portable, UL Class 350 1-Hour fire and water-resistant home for legal-size documents and digital media. At 7.3 by 19.9 by 17 inches and 56 pounds, it fits on a closet shelf yet stays grab-and-go ready.
If you store letter-size paperwork or want a lighter option, the smaller SureSeal SS103 is a more compact alternative within the same line.
