Abstract
A ventilation closure device for a telecommunication equipment enclosure includes opposed planar panels and aligned openings through each of the panels for passage of air therethrough for ventilating ambient atmospheric air to or from an equipment enclosure. One or more closures are disposed between the opposed panels and adapted to be drawn across the aligned openings for preventing passage of air, and a pivotal attachment to the closures disposes the closure into alignment with the opening. An actuator pivots the closures between an open position for allowing air passage through the openings and a closed position for impeding airflow. The pivotal attachment counterbalances the closures for mitigating force to pivot the closures. Counterbalancing of the closures minimizes actuation force required for drawing the closures across the openings.
