SR2POST 2-Post SmartRack Open Frame Rack is an economical way to accommodate 45U of rack space for 19-inch rack-mount applications where space is at a premium. Its heavy-duty, aluminum construction can safely support 8 pounds (362.9 kilograms) of rack-mount equipment. The black, textured power coat finish makes it resistant to scratching while giving it a classic, attractive appearance. The SR2POST is easy to install due to a self-squaring design combined with 12-24 threaded and numbered mounting holes, and bolt down provisions. Only standard hand tools are required for installation (9/16" wrench and 9/16" socket/ratchet). Multiple units can be bolted together side by side for easy expansion or customization when required. The SR2POST 2-Post SmartRack Open Frame Rack has been approved by EIA-31-D, IEC 6297-3-1, and RoHS. * 45U 2-post open frame rack * Black aluminum with 12-24 threaded and numbered mounting holes * Toolless button keyhole mounting slots accept PDUs or cable managers
