folder tray

Most are made from plastic or steel. There are also acrylic and polyurethane document holders available, though plastic and steel constructions are more common and often noted in product listings.

Many file boxes and document holders are sized for standard 8.5" x 11" (letter) paper. Several file boxes explicitly accommodate both letter and legal hanging folders.

Several file boxes include hinged lids with snap or tight-fit latches to secure contents and reduce dust. Some lids also feature indexed covers or small built-in compartments for quick-access items.

Many file boxes and crates include built-in carrying features such as sturdy handles with comfort grips, contoured grip areas, or integrated cutout handles on mesh crates to make them easier to move.

Care varies by product, but at least one clear plastic tray lists hand wash, spot clean, or wipe clean. Many organizers are easy to maintain with routine wipe-downs or spot cleaning.
