  • Underwriters Laboratories® (UL) Fire & Impact Rated to protect paper contents. When exposed to external temperatures of over 1700 degrees, the internal temperature of the cabinet will not exceed 350 degrees for the number of hours it is listed (paper ignites at around 480 degrees). The duration and maximum temperature of a fire in a building compartment depends on several factors and the cabinet may protect the contents for a longer period of time.
  • Fireproof File Insulation is 100% gypsum, reinforced by a 1" x 2" lattice made of 14-gauge, galvanized welded-steel wire, providing complete peace of mind from fire, impact or explosion.
  • Water Resistance means that the file cabinet is designed to prevent water damage resulting from sprinklers and fire hoses.
  • Field Replaceable Steel Panels allow for easy replacement of damaged panels.
  • Drawer Lock is a cam lock. Non-upgradeable.
  • Finish is both environmentally friendly and scratch-resistant, providing a lifetime quality appearance.
  • Drawer Bodies are built with high sides for use with hanging folders; no additional frames are required.
  • Insulation Between All Drawers makes each drawer a separate insulated container.
  • Made in the USA.

Rating Summary
  • Good value for a fireproof file cabinet
    Verified Buyer 17 May, 2019

    I purchased two fireproof file cabinets to store business documents. I liked how DigitalBuyer made it easy to compare different models and options. That made it easier to make a decision on which one to buy. The prices were good.

  • Fast shipping-GREAT PRICE
    Verified Buyer 19 May, 2017

    It was very fast shipping and the price was a good bit less than any other company we looked at! It was damaged when it arrived but it was on the side and did not effect functionality.

  • Fireproof Letter Filing Cabinet
    Verified Buyer 28 October, 2016

    This cabinet is everything as described. Really heavy duty.

    Shipping was very easy. They deliver in front of door on a pallet and all we have to do was use a dolly to put in building. Very heavy but as long as you have 2 men to help the work is completed.

  • Excellent
    Verified Buyer 06 August, 2016

    I purchased this fireproof filing cabinet because I know the FireKing brand and have had excellent results with it. Based on past experience with other vendors, I thought that it would take a while to receive the filing cabinet and that shipping would be tricky. Other sites offer free shipping, then quickly start to tack on fees for delivery if you need the item brought off the truck, etc. Not here. First, the item was ready for delivery immediately and I received it within a few days of placing the order. This was lightning fast and I was shocked. Second, there were no fees tacked-on and there was no hassle at the time of delivery. The driver brought the cabinet off the truck and was very helpful. I couldn't have asked for a better experience.

  • Great price, Great product
    Verified Buyer 14 July, 2016 was quick getting the file cabinet delivered, and the cabinet was delivered complete and ready to go as expected. It is a very quality, solid made fireproof file cabinet.
