The product is a used row of five APC AR3355 server rack cabinet enclosures, and are fully functional and are in "B" grade condition. These freestanding racks have a 45U rack unit height and 19-inch rack unit width. Only two of the 5 racks have side panels, and ideally would be used on the outsides of this row of 5 racks, leaving the interior racks without side panels, and are ideal for organizing and housing servers in an enterprise networking setup.
