heavy duty portable file box

Listings commonly show combination locks (including 3-digit combos), password-settable combo locks, zipper designs that can be locked, and separate lockable compartments for added protection.

Most listings accept standard letter-size documents (8.5 x 11 in) and many also accommodate legal-size files. Some product pages explicitly state compatibility with both letter and legal formats.

Capacity is often listed in quarts and varies across models. Examples in the results include about 11 quart and 22 quart units up to larger entries around 55 quart — roughly spanning the low teens to the mid-50s in quart values.

It depends on the construction: cardboard/paperboard boxes often require adult assembly but usually no tools, while molded plastic or rigid totes typically arrive fully assembled and need no setup.

Dimensions vary widely by model. Example sizes in the results include 14 x 14 x 17 in (H x W x D) and several other measurements such as 3.35 x 11.22 x 15.75 in, 10 x 12.5 x 16.25 in, 10.75 x 14.13 x 18.13 in, and 10.88 x 14.5 x 17.94 in. Always check the specific product listing for exact external dimensions.

Common materials include polyester fabric, EVA (Ethylene Vinyl Acetate), cardboard/paperboard, and molded or hard plastics. Fireproof or insulated models may add layers such as silicone-coated fiberglass, fire-resistant fabric or EVA foam and internal polypropylene (PP) support.

Product descriptions cite protection via fire-resistant exteriors or insulated linings and water-resistant or waterproof covers. Some listings make specific claims (one cites very high-temperature resistance, another references UL-94 VTM-0 insulation or IPX4 water resistance). Verify each product’s stated ratings and test standards on its detail page.

Descriptions commonly highlight tear-resistant exteriors, reinforced or impact-resistant hard shells that resist crushing, and water-resistant or waterproof covers to protect contents from spills and moisture.

Customers frequently describe build quality as sturdy and suitable for stacking, and often report easy assembly and everyday use. Some reviews mention occasional issues with lid latching or limited durability of particular parts, so check reviews for model-specific feedback.
