Retractable Cone Bar: This retractable traffic cone bar extends from 3.94 ft to 6.89 ft with an extendable design. Easy to use, it places between cones to create longer barriers and fits any and all traffic cones. Material: Made from environmentally friendly PVC, the retractable cone bars are solid, stable, and lightweight. They are weather resistant and won't fade or crack easily, providing longlasting performance. Visible: The cone bar is reflective for optimum visibility and safety in dark and night conditions. It remains visible even in mud, fog, rain, snow, or other adverse conditions. Easy to Use: Fits over many different types of traffic cones using builtin plastic rings at both ends. Use scenarios: Road construction and maintenance zones: quickly extend barrier length between cones to create clear, visible lane demarcations. Outdoor events and parking areas: cordon off restricted zones and direct pedestrian or vehicle flow with flexible spacing. Emergency response and roadside assistance: establish safe perimeters rapidly in low visibility or harsh weather conditions.
