    Abstract: A portable net holding assembly for volley ball and the like comprises two identical halves. Each half of the assembly includes a substantially planar base member having (i) at least one downwardly depending spike adaptable for insertion into the ground adjacent the playing area in order to secure or hold the base to the ground when in a deployed position or playing position, and (ii) an upwardly depending, centrally located male stud.
