Durable, visible Rhino Barriers from PolyJohn Enterprises can help keep vehicular or pedestrian traffic in or out. These tough barriers can be used on construction sites, for roadwork, airports and special events. They are lightweight and easy to handle, which means that just one person can position a barrier. They’re also easy to stack and store. They are manufactured from strong, molded polyethylene and can be custom designed in a variety of highly visible colors. A hinge pin makes them easy to install. The special pin system tightly interlocks each barrier for proven strength. They can be filled with water or sand for added weight and security. They come with safety reflectors, warning lights and room for company signage. 800/292-1305; www.polyjohn.com.
