FireKing Classic Fireproof File Cabinet, 4-Drawer, 25" Deep for Letter Files (4-1825-C)

FireKing Classic 4-1825-C Fireproof File Cabinet, 4-Drawer, Letter Size, 25″ Deep

The FireKing Classic 4-1825-C is a four-drawer, letter-size fireproof file cabinet that delivers FireKing’s high-security construction in a space-efficient 25-inch depth. It combines UL Class 350 one-hour fire protection, UL 30-foot impact resistance, explosion resistance, water-resistant insulated construction, and independent drawer protection for critical paper records.

This compact-depth model is designed for letter-size hanging folders and provides substantial protected filing capacity without extending as far into an aisle as a 31-inch cabinet. A UL-listed high-security key lock is standard, with combination-dial and electronic-lock upgrades available. Field-replaceable steel panels, maintenance-free drawer suspensions, and numerous finish choices distinguish the Classic series from FireKing’s more streamlined Patriot line.

• Four-drawer capacity: Provides substantial protected letter-size storage within a traditional vertical footprint.
• Compact 25-inch depth: Reduces cabinet projection and preserves more aisle space than a full-depth 31-inch model.
• High-security locking: A UL-listed key lock is standard, with combination-dial and electronic-lock upgrades available.
• Independent drawer protection: Each closed drawer remains its own sealed, insulated compartment when another drawer is open.

Common Applications

The 4-1825-C is designed for organizations that need high-capacity letter-size filing with certified fire protection and stronger security options than a value-series cabinet provides.

• Legal, accounting, and financial records
• Medical and administrative files
• Human resources and personnel records
• Government and municipal documents
• Schools, colleges, and universities
• Business records rooms with limited aisle space

Choosing the Right FireKing File Cabinet

Letter Size vs. Legal Size

The 4-1825-C is the narrower letter-size version. Choose the wider 4-2125-C when legal-size filing is required.

25″ vs. 31″ Depth

Choose this 25-inch model when conserving aisle space is important. Choose a 31-inch-deep FireKing Classic cabinet when greater filing capacity per drawer is the priority.

FireKing Classic vs. Patriot

Choose the Classic series for a UL-listed high-security key lock, optional combination or electronic locks, additional finish choices, and FireKing’s full-featured construction. Choose Patriot when a simpler, more economical configuration meets your requirements.

Delivery and Site Access

At 478 lbs., the 4-1825-C ships by freight and requires delivery planning. Select the service level that matches your unloading capabilities, building access, and desired final placement.

• Loading-Dock Delivery: Best for commercial facilities equipped to unload and move the palletized cabinet.
• Liftgate or Curbside Delivery: The cabinet is lowered to ground level and left palletized for the customer to move inside.
• Lobby or Garage Delivery: The cabinet is moved into the first accessible covered area when site conditions permit.
• Full-Service Delivery: Includes movement to an approved final location, placement, and packaging removal when site conditions permit.

Confirm access before shipment. Residential delivery, stairs, restricted truck access, narrow doors, tight turns, long carries, floor protection, or other unusual conditions may require additional review or charges. Standard freight service may use a 53-foot tractor-trailer.

Warranty and After-Fire Protection

The FireKing Classic cabinet is covered by a limited lifetime warranty, with FireKing’s commitment to cover associated labor costs for two years after purchase. Eligibility requirements, exclusions, authorization procedures, and current written terms apply.

If the cabinet is damaged by fire while owned by the original purchaser, FireKing’s Free After-Fire Replacement Guarantee provides a replacement cabinet at no charge. The replacement ships freight collect, and proof of original purchase and claim validation are required.
