Keep documents, supplies, and daily work essentials sorted and secure with this rolling three-drawer file cabinet designed to slide beneath standard desks. Two compact upper drawers hold pens, notepads, and small accessories, while the full-extension lower drawer accommodates letter, legal, and A4 hanging files with an adjustable rail. A keyed lock secures two drawers for confidential storage, and four smooth-rolling casters with two braking wheels let you reposition the unit or lock it in place as your workflow shifts.
