Many file boxes and crates are designed for portability, with integrated handles or contoured grips for easy carrying. Several models also have indexed tops or covers and are built to stack securely for efficient vertical storage.
Binder and pocket dividers commonly include 3-hole punching to fit binders, clear-view pockets, erasable or write-on tabs, multicolored tabs for quick reference, and durable plastic construction to withstand frequent handling.
Most items are sized for standard letter paper (8.5" x 11"). Several portable file boxes explicitly accommodate hanging letter-size folders, and at least one model is described as accommodating both letter and legal-size hanging folders.
File boxes commonly use latches or tight-fitting lids to secure contents. Some listings note durable latches and lids that can accommodate a small padlock or a zip tie for added security.
Many portable file boxes, folders, document holders, and mesh crates list "No assembly required." Furniture-style filing cabinets typically require adult assembly and often note that tools are not provided.
