ABSTRACT:
Panel members for plugging the ventilation ports of animal-carrying vehicles. Locking tabs on the panel-periphery are sufficiently resiliently flexible as to be easily pushed across the edge of the truck's ventilation port, making installation easy for winterizing the truck by covering the truck's wall ports; and the resilient flexibility of the tabs permits an easy summerizing of the truck by being easily knocked out to re-open the wall ports. The resilient flexibility of the tabs permits repetitive use.
