This stack-on hutch can be mounted to any base unit of the same size. Designed to be installed on top of a desk or credenza; not intended to be used freestanding on the floor. Fully finished on all sides so it looks good from any angle. Stores important materials above the worksurface and within easy reach. Self-closing door mechanisms are designed to keep doors shut and neatly aligned when not in use. Doors are mounted on high-quality, chrome-plated European hinges to operate smoothly.
