file cabinet box

Lock and security options vary by product. Portable boxes may accept a small padlock or use a built-in combination lock; some boxes have double-layer locking compartments. Many cabinets use a single lock that secures all drawers or a central locking system to protect contents.

Portable boxes typically include built-in handles and may be collapsible or lightweight for carrying. Some cabinets offer caster wheels (often with front-wheel brakes) to make repositioning easier.

Space-saving designs include slim vertical cabinets for tight footprints, portable boxes with indexed lids that allow secure stacking, and collapsible file boxes that fold flat when not in use.

Many listings accept standard Letter-size files; several explicitly note Legal-size compatibility; and a number of cabinets and boxes list A4 compatibility or include adjustable rails to fit A4, Letter and Legal folders.

Some document boxes are described as fireproof and water-resistant. For example, at least one box is built from double-layer silicone-coated fiberglass and is advertised as withstanding very high temperatures; it also includes a combination lock and multiple internal pockets. Separately, some plastic file boxes feature tight-fit snap lids and indexed tops to help keep out dust and moisture.

Assembly varies by product: many metal and wood cabinets list 'Adult Assembly Required' (tools may or may not be included), while many plastic file boxes and some steel crates arrive with 'No Assembly Required.'
