A screen or cover is provided for use on vehicles to cover the side of a trailer and the like to protect the contents such as automobiles. The screen also enhances the aerodynamic efficiency of the vehicle and includes a panel having peripheral tubes extending between the selected locations on the periphery of the panel and coupled to the panel. The periphery of the panel between adjacent pairs of the selected locations is cut back from the intended final position of the periphery and at least one cable is threaded through the peripheral tubes. Button means are provided for attachment to the side of the trailer at positions to receive and support the cable where the cable is exposed at the selected locations, and means adapted to tension the cable is provided. This last means is used to draw the cable tight over the buttons so that the panel is tensioned as the cable is pulled straight against the resistance of the panel where it is cut back between the buttons.
