When Jack Kulp founded TrafFix Devices in 1987, one of his major goals was to design and manufacture all products within the United States. With that goal in mind, TrafFix Devices is now one of the largest producers of road safety products in the world. Jack and the TrafFix Devices Engineering Team are constantly hard at work designing and engineering products that will revolutionized the construction and traffic safety industries.
These are just a few of the innovative products we have created...
In 2002, Jack's goal proved to be difficult when work began on a weather resistant channelizer cone. Todays' standard for channelizer cones, between 18" and 36", is to use PVC for its low cost, and high durability; because of its low cost, many PVC manufacturers have moved away from the US to keep their costs down. While PVC is a strong and durable plastic, it does not hold up well when exposed to hot and cold temperatures. PVC cones break when temperatures drop below 0°F. When temperatures are above 100°F, PVC cones to “droop” and lose their structural integrity. At more extreme temperatures, over 120°F, PVC has been known to melt to road surfaces. Over the years, we worked with a number of different PVC manufacturers to design a PVC cone that would outlast and outperform similar products on the market; however, PVC could not stand up to the temperature ranges we desired.
We then had a novel idea: Why do we have to use PVC? TrafFix Devices already manufactures a wide range of polyethylene products; the tools, skill set, and knowledge were already available. Over the next few years, TrafFix Devices worked tirelessly to create a polyethylene cone that was strong, durable, flexible, and could withstand a wide range of temperatures. Low-density polyethylene (LDPE) proved to be the exact material we needed to effectively create and all weather cone.
With its ingenious “break-apart” design, the Enviro-Cone can separate from its base when impacted by a vehicle. This reduces the chance of the cone being destroyed when impacted by a vehicle. If a stem is ever destroyed, simply reorder the stem and reuse the base. Since it's release in early 2014, the 28” Enviro-Cone has received extremely positive feedback from customers.
Not only has the Enviro-Cone surpassed its intended goal, it has pushed the company into a new direction: Environmentally friendly traffic safety products.
In 2015, TrafFix Devices released 18" and 36" Enviro-Cones.
