The foldable warning cone (10) is formed from paper, thin plastic, fabric, or a combination thereof, and includes two tapered side panels (12) and a base panel (14). The base panel (14) extends between the lower edges (34) of the side panels and includes a central folding seam (16), which allows the base panel to be folded upward so that the cone can collapse into a very thin configuration. One or more crimp line extends along the side panels to provide increased strength for increased life especially in wet weather. |
