Patent abstract
An impact head for a guardrail includes cable routing means adapted to form a convoluted path through which a cable can be threaded. The convoluted path that the cables must follow through the impact head of the invention restricts movement of the cable through the head, thereby providing sufficient friction to slow down the movement of the impact head during a vehicle impact.
