The Mr. Chain Plastic Stanchion Kit is an effective and cost-effective crowd control solution for both indoor and outdoor events. This kit includes four 41-inch tall stanchion posts with 16-inch bases made of durable and lightweight high-density polyethylene. Two c-hooks on the top of each stanchion allow you easily attach the included 30-foot heavy duty plastic chain and run it in a continuous length. Great for sporting events, parking lots, malls, theaters, construction sites, schools, hotels, and more, this stanchion set is perfect for forming lines, directing crowds, or restricting access to protect people and property. The polyethylene design is made with UV inhibitors for long-lasting outdoor use.
