In an immediate situation, deploy a bar—placed between two traffic cones—to create a quick and temporary visible barrier. The Barrier Cone Bar from ACCUFORM SIGNS sets up instantly to mark off temporary hazardous areas and work zones around plants and facilities. It's easy to set up—simply place the open ring-ends of the bar over the tops of two traffic cones, creating an immediate barrier expandable to 6-1/2 feet. Reflective alternating stripes provide added visibility with contrasting colors that can be seen in low-light conditions. The Barrier Cone Bar is 1-1/2" diameter molded plastic with 3-1/4" diameter plastic rings on both ends to fit over the top of traffic cones. Telescopic bar opens to a maximum of 6-1/2 feet and collapses to 4 feet for lightweight portability and storage.
