Abstract
A guardrail includes a cable routing device providing a tortuous path for at least one tensioned cable, the cable routing device includes a bar having a rotational axis and including a cable entry port having a circumference slightly larger than the cable which passes directly therethrough when the bar is in a first non-cable gripping orientation in which the diameter of the port (diametric width) is substantially orthogonal to the longitudinal axis of the cable, and wherein rotation of the bar about the axis effectively decreases the width of the port relative to the width of the cable to create a second cable-gripping orientation which provides the tortuous path, wherein the tortuous path through the bar is due to the relative decrease in the effective diametric width of the port and this provides sufficient frictional resistance to movement in relation to the cable during impact to facilitate impact energy dissipation.
