The DataPro 80-3424 Super-Size Shelf
fits an industry standard 19 inch rack.
Conforming to EIA-310C standards, these rack
shelves are made of heavy duty 6061-T6
extruded aluminum in a natural mill finish. They're not
sleek and glossy for looking pretty on a date—they're
rugged, industrial, and ready for heavy loads.
When fully mounted, the shelf unit
measures 19W x 21D. This is
also called a center-weight shelf, as
it mounts with its weight approximately
balanced between front and back.
This shelf consists of two separate pieces,
each 10.5 inches deep, which are intended to
mount back-to-back to form a 21-inch deep
shelf. In this configuration, it can hold
up to 150 pounds.
It is also possible to mount each piece
separately to make two smaller shelves.
