The FireKing 4-2131-CSF is the best Safe-In-A-File option when you need maximum protected filing capacity along with a concealed safe compartment. It gives you the filing space of a full 4-drawer legal-size fireproof cabinet while adding discreet internal safe storage behind the top drawer front.

This design is especially useful for offices that store important records and sensitive valuables in the same area. Instead of purchasing a separate safe and file cabinet, this model keeps everything organized, protected, and accessible in one fire-rated cabinet.

The concealed safe compartment is ideal for cash, checks, backup media, deeds, passports, confidential records, small valuables, and other sensitive items that should not be stored in a standard file drawer.

Built-in filing and hidden security in one cabinet. The 4-2131-CSF is designed to protect legal-size records, sensitive documents, and concealed valuables from fire, impact, water exposure, and unauthorized access.
