Abstract
An improved anchor for embedment in a concrete member to provide a lifting attachment for the member. The anchor comprises an elongate bar having convergent and divergent surfaces wherein the divergent surfaces face outwardly to direct axial pull-out forces imparted to the bar divergently and laterally into a concrete member within which the anchor is embedded. Divergent wings are fixed to and extend laterally from the bar to direct lateral forces imparted to the bar in divergent directions relative to the bar.
