Some embodiments generally relate to a hook assembly, including a pivotable hook body adapted to rotate about a pivot axis running in a generally vertical direction. According to some embodiments, the hook assembly can further include at least one hook portion including a generally vertical recess defined by a portion of the top side of the hook body extending downwardly toward a bottom side. The assembly can further include a pivot member for pivoting the pivotable hook body about the pivot axis; and a frame member adapted to receive the pivotable hook body in a stowed configuration or one or more deployed configurations. Furthermore, frame member is adapted to fix the hook body in a pivotal relation about the pivot axis and can include an indexing opening or seat for defining one or more indexed orientations such as a stowed orientation or a deployed orientation.
