A lifting anchor for a precast concrete structure is made from a single strand of metal bar stock. The anchor includes undulations or waves that ensure proper engagement of the anchor in a desired compressed concrete zone and also minimizes interference with the pre-stressed strands in the concrete structure. The anchor can be positioned in different orientations in the structures, depending on functional requirements of particular structures, and can be made from a single strand of bar stock of desired cross-sectional thickness and shape (e.g., round or square). Also, the undulations or waves in the legs of the anchor can extend in one or both directions from a plane defined by the anchor's legs.
