SR2POST 2-Post SmartRack Open Frame Rack is an economical way to accommodate 45U of rack space for 19" rack-mount applications where space is at a premium. Its heavy-duty, aluminum construction can safely support 800 lb (362.9 kg) 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-310-D, IEC 60297-3-100, and RoHS.
