A system for displaying a desired reflective sheeting striping pattern on a traffic management device includes providing a portable panel having reflecting sheeting affixed to a face thereof, orienting the portable panel as desired, and affixing the panel to the device using fastener holes disposed about a perimeter of the panel. The displayed striping pattern may be easily changed by removing the panel from the device, turning the panel over to display an opposing side, on which is displayed a different striping pattern, and reattaching the panel to the traffic management device so that the opposing side of the panel is displayed, or by removing the panel from the traffic management device, rotating the panel by 90 degrees, 180 degrees, or 270 degrees, and then reattaching the panel to the traffic management device so that the same particular striping pattern is oriented in a different direction.
