FireKing 3-2131-C-SF 3-Drawer Safe-In-A-File Cabinet

The FireKing® 3-2131-CSF Safe-In-A-File Fireproof File Cabinet combines legal-size fireproof filing with a concealed built-in safe. This 3-drawer cabinet is designed for offices, law firms, financial offices, medical offices, home offices, and small businesses that need protected file storage plus a discreet place for valuables, cash, backup media, deeds, passports, checks, or sensitive documents.

The hidden safe is located behind the false top drawer front and provides approximately 2.44 cubic feet of concealed storage. Below the safe compartment are legal-size fireproof file drawers for everyday protected filing.

This model is a practical choice when you need more file capacity than a 2-drawer Safe-In-A-File cabinet, but do not need the full height or weight of a 4-drawer model. It gives you fire-rated filing and hidden secure storage in one professional office cabinet.

Fire and Security Protection

The FireKing 3-2131-CSF is built to protect important paper records, sensitive documents, and concealed valuables from fire, impact, water exposure, and unauthorized access. The UL Class 350 1-hour fire rating helps protect paper documents during severe fire exposure, making this cabinet useful for legal files, financial records, medical records, HR documents, tax records, contracts, deeds, titles, and other important business paperwork.

This cabinet is also 30-foot impact tested to help maintain cabinet integrity in conditions associated with building fires, falling debris, or structural collapse. Water resistance is another important benefit because sprinklers and fire hoses can damage records even when flames do not directly reach the cabinet.

The concealed safe adds a separate layer of protection for valuables and sensitive items that should not be stored in a standard file drawer. The safe is hidden behind the false top drawer front and is built with a 3/16" hot rolled steel body and 1/4" thick steel door.

Filing Features and Daily Use

• Concealed internal safe provides hidden storage for valuables, cash, checks, backup media, deeds, passports, and confidential records.
• Legal-size filing supports 8.5" x 14" hanging folders.
• 3-drawer vertical design balances protected filing capacity with a smaller footprint than a full-height 4-drawer cabinet.
• High-side drawer construction allows hanging folders to fit without additional frames.
• Medeco® high-security drawer locks help secure sensitive file drawers.
• UL-listed safe lock provides secure access to the hidden safe compartment.
• Digital media verification provides 30-minute ETL fire protection for CDs, DVDs, and flash drives.

The FireKing 3-2131-CSF is useful for organizing files by client, case, department, employee, account, property, year, or record type while keeping highly sensitive items secured in the concealed safe compartment.

Construction and Cabinet Features

FireKing Safe-In-A-File cabinets are built for long-term office use, fire resistance, impact protection, and secure document storage. This model includes independently insulated drawers, high-side drawer construction, maintenance-free drawer suspension, field-replaceable steel panels, and a scratch-resistant electrostatic powder-coated finish.

The cabinet includes a 2-position drawer catch for selective access, surface-mounted drawer pulls designed to allow added insulation inside the drawer heads, Medeco® high-security drawer locks, and a UL-listed dial combination lock for the concealed safe. An electronic safe lock upgrade is available for users who prefer keypad access.

Delivery Information

This cabinet ships by freight and weighs 644 lbs. Before ordering, please confirm your receiving hours, truck access, doorway clearance, elevator access, floor load concerns, and final placement location. Choosing the correct delivery service helps avoid delays, added costs, or delivery issues.

Delivery Options

• Loading Dock or Curbside Delivery: Best for commercial locations with a loading dock, forklift, or accessible curbside freight area. The cabinet is delivered on a pallet, and the customer is responsible for moving it from the delivery point.
• Inside Doorway or Garage Delivery: Available as an upgrade for qualifying locations. The cabinet is moved just inside the first accessible doorway, lobby, receiving area, or garage. The cabinet remains packaged and on the pallet.
• Full-Service Set-in-Place Delivery: Available as an upgrade for qualifying locations with ground-floor or elevator access. This service includes uncartoning, placement, and removal of packaging materials.

Step Limit: Inside delivery and full-service delivery are limited to no more than 3 steps up or down. If your delivery requires more than 3 steps, stairs, tight turns, long carries, restricted truck access, floor protection, a certificate of insurance, a special appointment request, or other unusual site conditions, please contact us before placing your order.

Residential Deliveries: Residential delivery is available; however, this item is a very heavy freight shipment and is best suited for curbside or garage delivery when shipping to a residence. If full-service residential delivery is needed, we may require a delivery review before shipment to confirm truck access, driveway access, doorway clearance, and a safe delivery path.

Please review doorway width, hallway turns, elevator access, floor load concerns, and the final placement location before selecting inside delivery or full-service delivery. If you are unsure which delivery option is right for your location, contact us before ordering.
