ABSTRACT:
A breakaway post base includes a pair of adjacent slip plates to allow separation of the upper portion of a traffic sign or the like from its permanently mounted base. The two plates are triangular with notches at their apices, with the plates and related structure secured together by bolts through the apex notches. An impact on the upper post dislodges the bolts, allowing the upper post to move freely and preventing significant damage to the sign structure. At least one of the slip base plates includes a sleeve extending therefrom, into which one end of the post is installed. The post is prevented from rotating relative to the slip base by a series of set screws installed through the slip base sleeve and locking the post immovably therein. Thus, a sign supported by the present assembly cannot rotate relative to the slip base plate.
