The Mr. Chain X-Treme Duty Stanchion is an effective, cost-effective solution for heavy-duty industrial applications. Ideal for military bases, construction zones, and manufacturing facilities, these highly visible stanchion posts are great for designating parking areas, creating barricades, and maximizing traffic control. Featuring a ribbed handle and wheeled base for portability, these stanchion posts stand 46.5 inches tall. Keyhole slots on the top of each stanchion allow you to easily attach a Mr. Chain plastic chain (sold separately) and run it in a continuous length, or you can cut the chain to length and hang it from the built-in C-hooks. The 2-gallon bladder in the base can be filled with water for additional stability. This crowd control stanchion is constructed with UV inhibitors for long-lasting outdoor use.
