Great for pedestrian traffic zones, parking lots, constructions sites, warehouses, and more, these lightweight and portable traffic cones, cone connectors, and chains are a cost-effective barrier solution. Simply slide the cone connectors over the top of the safety cones and attach the brightly-colored plastic chain. The distinctive visual barrier allows you to block off a larger area with less cones by spacing the cones farther apart. JBC Revolution Series Cones are the leader in the traffic safety industry as they are made from an innovative injection molded design that holds up in all temperatures and maintains color in difficult UV situations.
