A hanger can include a unitary bar extending between first and second opposite ends and between top and bottom surfaces. The hanger can also include a suspending member having a shank fixed to the unitary bar. The hanger can also include a first and second series of curved notches respectively disposed at the first and second opposite ends. The hanger can also include a bidirectional notch extending into the unitary bar from the bottom surface at a position between the first and second opposite ends. The bidirectional notch can extend vertically for a first predetermined distance and laterally for a second predetermined distance. An upwardly-facing surface can be defined by the bidirectional notch and is positioned lower than the first and second series of curved notches.
