CA 2020516

ABSTRACT The breakaway assembly includes a cast aluminum base having a collar for supporting a wrought aluminum standard and a base flange for securing the breakaway assembly to a plurality of anchor bolts projecting from a concrete foundation. The base flange includes a plurality of apertures for receiving the anchor bolts. Grooves are provided in the base flange adjacent the anchor bolt apertures. Upon impact, the standard creases and bends causing the heel of the base flange to lift. This lifting motion shears the base flange at the grooves to permit the base to lift away from the anchor bolts.
