Portable File Storage

The IRIS USA portable file storage set includes four black plastic boxes built to hold letter and legal size documents. Each box is moulded from anti-break polypropylene made in the USA with global materials. A rim ledge allows hanging files to slide on and off smoothly. The secure wing-lid and buckle keep contents protected during transport or stacking.

Sustained Load Behaviour

Under continuous daily use the polypropylene shell resists cracking and the rim ledge maintains its shape so hanging folders stay aligned. The latching buckle holds the lid tight even when boxes are filled to capacity and stacked several high. Handles remain firmly attached to the lid, allowing repeated carrying without stress fractures. The organiser lid compartments keep small supplies accessible without spilling when the box is moved.

Thermals Noise and Power

As a passive storage product the boxes generate no heat, produce no noise and draw no power. The BPA-free plastic remains stable in normal indoor temperatures and does not warp under typical office conditions. The weathertight seal helps protect documents from humidity and dust without any active components.

Questions about this item

Will the polypropylene boxes and their latching buckles soften or warp if they sit in a warm office all day?

The boxes are moulded from anti-break polypropylene made in the USA; this material resists softening or warping at normal indoor temperatures, and the secure wing-lid with buckle stays rigid during continuous use.

Do I need to buy hanging-file rails or folders separately to use the built-in ledge?

The rim ledge is sized for standard letter and legal hanging files, so you only need the files themselves — no extra rails or hardware are required.

Can I stack these on top of older cardboard archive boxes without the lids bowing?

The durable wing-lid and reinforced polypropylene walls support stacking; the secure buckles keep the lids flat so older boxes underneath are not crushed.
