FireKing 4-2131-C-SF 4-Drawer Safe-In-A-File Cabinet

The FireKing® 4-2131-CSF Safe-In-A-File Fireproof File Cabinet combines high-capacity legal-size fireproof filing with a concealed built-in safe. This 4-drawer cabinet is designed for offices, law firms, medical offices, financial institutions, schools, government offices, and businesses that need protected document storage plus hidden secure storage in one cabinet.

The hidden safe is located behind the false top drawer front and provides approximately 2.44 cubic feet of concealed storage for cash, checks, backup media, deeds, passports, confidential records, and other sensitive items. The remaining drawers provide fire-rated filing space for legal-size hanging folders.

This model is a strong choice when you need the filing capacity of a full-height vertical fireproof file cabinet with the added security of a discreet internal safe. It keeps important files and valuables protected in the same footprint without adding a separate visible safe to the room.

Fire and Security Protection

The FireKing 4-2131-CSF is built for serious protection of legal-size business records and sensitive valuables. 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 files, contracts, deeds, titles, school records, tax records, and other important documents.

This cabinet is also 30-foot drop 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 security for valuables and sensitive items that should not be stored in a standard file drawer. The safe is built with a 3/16" steel body and 1/4" steel door and is hidden behind the false top drawer front.

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.
• 4-drawer vertical design provides high-capacity filing in a compact floor footprint.
• High-side drawer construction allows hanging folders to fit without additional frames.
• Medeco® high-security drawer locks help protect 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 4-2131-CSF is a practical option when an office needs both everyday filing access and discreet protected storage. Files can be organized by client, case, department, employee, account, property, year, or record type while valuables and highly sensitive items remain secured in the concealed safe.

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. The cabinet includes fire-resistant insulation, high-side drawers for hanging folders, a durable powder-coated finish, and a hidden safe compartment with a steel body and steel door.

The file drawers use Medeco® high-security key locks, while the concealed safe includes a UL-listed dial combination lock. An electronic safe lock upgrade is available for users who prefer keypad access. The electrostatic powder-coated finish gives the cabinet a professional office appearance while helping resist scratches and wear.

Delivery Information

This cabinet ships by freight and weighs 728 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.
