ABSTRACT:
A post for ground insertion having a plate which swings outwardly from the post upon upward movement of the post to prevent post extraction. An inclined surface of the plate is acted upon by earthen material for plate deployment. A limit stop positions the plate substantially perpendicular to the post. The plate may consist of overlapped plate members to provide a rigid or non-bendable portion. A bendable portion of the plate bends during upward movement of the post during setting of the post. Such bending occurs about perpendicularly oriented axes.
