  • Patent number: 5451118
    Abstract: An improved two-piece, detachable traffic device features a high-density, low-profile solid base. The base is, preferably, made of a molded unitary composition made of recycled rubber products, such as, spent motor vehicle tires. Further, it is molded such that it can be stacked for ease of storage with similar bases. The combined high-density and low profile aspects of the base cooperate to ensure both that the base remains stationary during use and can easily be traveled over by a vehicle without damage resulting to the base or the vehicle.
