Tripp Lite's SR2POST13 2-Post SmartRack Open Frame Rack is an economical way to accommodate 13U of rack space for 19-inch rackmount applications in limited spaces. Its heavy-duty, aluminum construction can safely support 800 lbs. of rackmount equipment. The black, textured powder coat finish makes it resistant to scratching while giving it a "classic," attractive appearance. The SR2POST13 is easy to install due to a self-squaring design combined with 12-24 threaded and numbered mounting positions along with 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 as needed. The SR2POST13 2-Post SmartRack Open Frame Rack has been approved by EIA-310-D, IEC 60297-3-100, and RoHS, and is backed by a 5-year warranty.
