The DataPro 80-3422 Full-Size Rack Shelf fits an industry standard
19 inch wide rack. It is a real shelf, perfect for shelfy things. Anything
that a normal shelf could be used for this one can too, but with the added
benefit of being on your computer rack.
If you place a black item on this shelf's flat-black finish and turn off the lights, the item
may be difficult to see. If you bang your hand on this medium-weight metal shelf while groping
around in the dark, you may injure yourself. This metal rack is tough stuff.
The dimensions are 19W x 19D, and the construction conforms to EIA-310C standards. This is also called a center-weight shelf, as
it mounts with its weight approximately balanced between front and back. It's
designed for center-load racks, so if you put it on a front-loading rack it's gonna
look weird. It'll work just fine, it'll just... look weird.
