Rhino Barriers from PolyJohn can be used to keep vehicle or pedestrian traffic in or out at construction sites, road projects, airports and special events. They are lightweight, are easy to handle, and can be positioned by a single person. They’re also easy to stack and store; are manufactured from durable, molded polyethylene; and can be custom-designed in a variety of high-visibility colors. A pin system tightly interlocks each barrier for strength. They can be filled with water or sand for added weight and security. Safety reflectors, warning lights and room for company signage are optional. 800-292-1305; www.polyjohn.com/rhino-barriers.
