Abstract
A card guide allowing or impeding airflow to a circuit card uses overlapping airflow shutters disposed longitudinally along the bottom of the card guide. The shutters are operated in response to the insertion of a card into the card guide by the action of a panel of the circuit card engaging an actuating member on the card guide assembly. When open, the shutters provide an opening which exceeds fifty percent of the airway.
