With solid four-post construction in a standard rack size at a very economical price, 4-Post Racks from Black Box are data center staples! Our 4-Post Rack combines the stability of a cabinet with the airflow of an open rack. It's tough, too - it's 12-gauge steel, quality construction supports more than a ton of equipment! The rack ships unassembled for easy transport to your site. Assembly is easy with the included hardware. You can install it as a standalone rack or bay it. To bay the rack, use our Baying Kit (RM7002-R2). The rack conforms to the EIA standard for 19" equipment mounting and features universal M6 mounting holes. It comes with 50 M6 cage nuts and screws for mounting.
