Abstract
Abstract A frame assembly for rack-mountable components. A rectangular top frame having a tubular perimeter is connected by four vertical rails to a bottom frame which also has a tubular perimeter as well as tubular members which span it. Both and top and bottom frames each provide an unobstructed central area which may be used for ventilation or application of electromagnetic shielding.
