The FireKing 3-2131-CSF is a practical choice when you need more protected filing capacity than the 2-drawer Safe-In-A-File model, but still want a concealed safe built into the cabinet. It gives you secure storage for valuables and sensitive items while still providing legal-size fireproof filing below.

The hidden safe compartment is ideal for cash, backup media, confidential documents, passports, deeds, checks, small valuables, or other items that should not be stored in a standard file drawer. Since the safe is hidden behind a false top drawer front, the cabinet maintains the appearance of a traditional fireproof file cabinet.

This model is especially useful for offices that want one cabinet to handle both protected records and discreet valuables storage without adding a separate safe.

Built-in security and fire protection in one cabinet. The 3-2131-CSF is designed to protect paper records, sensitive documents, and concealed valuables from fire, impact, water exposure, and unauthorized access.

• Concealed Safe Construction: Built-in safe features a 3/16" hot rolled steel body and 1/4" thick steel door
• Independent Insulation: Each drawer is insulated separately for added fire protection
• Fire Protection: UL Class 350 1-hour rating at 1700°F
• Impact Protection: 30-foot impact test with cabinet integrity maintained
• Water Resistance: ETL verified protection against fire hoses and sprinkler exposure
• Digital Media Protection: ETL verified for 30 minutes for CDs, DVDs, and flash drives
