Cabinets on tracks are a smart choice for saving space and flexible office storage. Their locking doors slide open into the sides of the cabinets. Inside the cabinet, you can store various items like file boxes, letter and legal-size files, notebooks, and all your office supplies and equipment. The cabinets are mounted onto movable bases that roll side-to-side on tracks. The cabinets on tracks are placed in front of stationary cabinets to maximize storage in the least amount of space.
