Mr. Chain heavy duty stowable stanchion is an effective and cost-effective traffic and crowd control solution for both indoor and outdoor events. The stowable stanchion is broken down for convenient storage and comes in one small box. The stanchion post stands 41 inches tall with a 14-inch hollow base that can be filled with sand for added stability. Two c-hooks on the top of each stanchion allow you easily attach plastic chain not included and run it in a continuous length. Great for sporting events, parking lots, malls, theatres, construction sites, schools, hotels, and more to protect people and property. The heavyweight, high-density polyethylene design is made with uv inhibitors for long-lasting outdoor use.
