ABSTRACT:
A load assembly for a self-uprighting delineator which moves from a first upright position to a second yielded or deflected position upon impact and returns to the upright position after impact. The assembly has upper and lower cell elements that have cooperating and complimentary alignment members in the form of notches and ridges. When the assembly is twisted, the alignment members cause the upper and lower cells to properly align the spring loaded cables passing through cable passages in the elements.
