Durable, visible Rhino Barriers from PolyJohn Enterprises are ideal for use on construction sites, roadwork, airports and special events. They are lightweight and easy to handle, and can be positioned by one person. They’re easy to stack and store, and are manufactured from strong, molded polyethylene that can be custom designed in a variety of highly visible colors. A hinge pin system tightly interlocks each barrier for strength. They can be filled with water or sand for added weight and security. They have safety reflectors, warning lights and room for company signage. 800/292-1305; www.rhinobarriers.com.
