ABSTRACT:
A one-piece molded plastic stake includes a slender elongate body formed of four integral webs which taper inwardly from a rounded striking surface at the trailing end of the stake to an intermediate point of the stake where the webs extend outwardly to provide a shoulder to resist pullout, once the stake has been driven into the ground. The webs taper inwardy from the outer ends of the outwardly extending portions and merge at a point at the leading end of the stake. Reinforcing portions are provided between the webs at the trailing end of the stake and provide for an enlarged striking area.
