Sturdy and Durable Structure The road sign post with base is made of PE material and the traffic cone is made of PP plastic material, which will not fade or crack and can withstand various weather conditions and environments. Traffic Cones: These cones are 1.5 m (4.9 ft) long and are manufactured by connecting cones 80 cm high. They are ideal for portable and temporary crowd control. Multiple cones can be connected to create longer barriers. EASY TO INSTALL - Traffic barrier posts feature two round holes that allow you to easily connect the connecting rod to the cone holes, thus improving traffic control. Quick assembly in seconds. SAFETY REFLECTIVE FILM - Our traffic sign posts feature a bright and eye-catching reflective film that can be seen from a distance and serves as a warning. When used in conjunction with reflective cones, it offers even sharper visibility. SUITABLE FOR INDOOR AND OUTDOOR: These tapered parking poles are perfect as portable parking poles for construction sites, driveways, stadiums, driving classes and equestrian training. Create a warning zone at your driveway or mark a safe area for children to play at the entrance or on the street.
