Buy these durable 18" orange traffic cones for use in directing traffic for construction sites, as an alert for road hazards, or as markers for parking lots and sporting events. These high visibility PVC injection molded cones are tough so they will last you a long time. Even after being run over by a truck they can rebound back to their original shape. These traffic cones won't separate from their base and have a rubber base that is designed to grip the road. Their design keeps them stable so they won't be blown over by winds and stackable for storage.
