Fireproof File Cabinet, 4-Drawer, Letter, 31" Deep, FireKing Classic 4-1831-C

The FireKing Classic 4-1831-C is designed for organizations that need substantial protected capacity for active letter-size records. Its 31-9/16" exterior depth provides 26" interior drawer depth, giving each of the four drawers substantial filing capacity.

Choosing your configuration

4-drawer vs. 2-drawer: choose the four-drawer 4-1831-C when you need maximum protected filing capacity within a single cabinet footprint. A two-drawer model is easier to place in a private office or smaller records area and has a lower overall height and weight.

31" vs. 25" depth: the full-depth Classic provides longer drawers and greater filing capacity. A 25-inch-deep cabinet is better suited to limited aisle space, compact offices, and delivery routes with tighter turns.

Letter vs. legal: the 4-1831-C is designed for letter-size records. Choose a wider legal-size FireKing Classic model when your records are primarily 8-1/2" x 14".

Classic vs. Patriot: the Classic line provides a UL-listed Medeco® high-security lock, optional lock upgrades, additional finish choices, and a broader range of configurations. FireKing Patriot models provide essential one-hour fire protection in a simpler configuration.

With an average shipping weight of approximately 603 lb., the FireKing 4-1831-C ships by freight and requires delivery planning. Confirm truck access, receiving hours, doorway and hallway clearance, turning space, floor conditions, elevator capacity, and final placement before shipment.

Access & placement

• Truck access: standard freight service may use a 53-foot tractor-trailer. Disclose locations that require smaller-truck service.
• Doorways: verify the narrowest opening along the complete delivery route.
• Hallways and turns: confirm adequate clearance for corners, narrow hallways, and long carries.
• Elevators: verify elevator door opening, interior dimensions, and weight capacity.
• Stairs or steps: disclose all stairs before shipment. Stair service may require additional review or charges.
• Floor conditions: place the cabinet on a level floor capable of supporting the cabinet and its fully loaded weight.
• Drawer clearance: allow enough space for drawers to open completely without blocking an aisle or doorway.
• Residential delivery: residential locations and unusual access conditions may require additional review.

Residential delivery, stairs, restricted truck access, tight turns, long carries, floor protection, or other unusual site conditions may result in additional charges.
