ABSTRACT:
A frangible coupling assembly for breakaway pole bases has a pair of spaced and parallel plate with a plurality of struts extending therebetween and being situated between a pole base and a supporting base. Each strut is of an elongated cross-section with the longitudinal axis of the struts lying on the perimeter of a circle concentric with the central vertical axis of the plates thereby providing an increased resistance to torsional loads and at the same time relatively lower resistance to lateral force.
