Abstract
A cable release anchor having an improved breakaway post design with a cable release feature. The cable release anchor includes upper and lower anchor portions that are readily separable from one another during an impact. A bearing plate is retained within the end of each of the upper and lower anchor portions, and each bearing plate has a bearing surface that is oriented at an acute angle with the vertical when installed in the ground. Each of these bearing plates contains a U-shaped cutout. When the upper and lower anchor portions are joined, the cutouts form an opening through which an end of the tension cable is disposed. An impact to the upper anchor portion readily releases the upper post section from the lower post section and frees the cable. The cable release anchor provides positive anchorage to react to tensile loads on a rail member to redirect a vehicle impacting along the length of the terminal or guardrail.
