one or more stainless steel stabilizer brackets positioned on said stabilizer rod;
wherein said front face comprises;
a jacking type screw; and
one or more moment pins;
wherein said connector end comprises;
a connector alignment pin;
a shear alignment pin;
I/O connectors; and
a pin guard;
wherein said top cover comprises;

Abstract
A chassis for circuit cards has a housing, a front end, a connector end, and a top cover. The housing has an airflow slot on its underside, and the top cover is open in nature, the combination of which allows the flow of forced convection air from top to bottom (or vice versa) to cool the circuit cards. The connector end has alignment pins which assist in blind mating of the chassis in difficult to access areas. Stabilizer rods, spacers and spacer brackets, made from stainless steel, hold the circuit cards in place and protect them from shock, vibration, and other trauma. The front end has a jacking type screw which enables one to exert sufficient pressure so that the greater than 200 I/O pins at the connector end are easily forced into receiving sockets.
