The Mr. Chain Cone Chain Connector Kit works with traffic cones of any size to create an effective visual barrier. Great for pedestrian traffic zones, parking lots, constructions sites, warehouses, and more, these lightweight and portable cone connectors are a cost-effective tool for isolating specific areas. Simply slide the cone connectors over the top of the safety cone (not included) and attach the brightly-colored plastic chain. The distinctive visual barrier allows you to block off a larger area with less cones by spacing them farther apart. If a car drives through the traffic cone chain, the chain will simply fall off of the connector an no damage will be done to the car. The Mr. Chain Cone Chain Connector Kit is made of durable, high-density polyethylene with UV inhibitors to protect it from fading in the sun and can be used indoors or outdoors.
