This 10-piece set of 28" traffic cones is designed for traffic control, parking lots, construction zones, schools, and roadside emergencies. Made from flexible PVC, the cones are built to handle moisture, oil, temperature extremes, and repeated outdoor use. Each cone features reflective collars for high visibility in day, night, and poor weather conditions. A large weighted base helps keep the cones upright in windy conditions, while the stackable design allows for easier storage and transport.
