ABSTRACT:
A hollow post tube 12 is reciprocable on an anchor spike 14 to implement the placement and removal of a sign post. A striker plate 20 located on the bottom of the post tube may be repeatedly hammered down against a ground abutment plate 16 or up against an impact plate 18, both secured on the anchor spike, to drive the anchor spike into or out of the ground. Planar ears 22 secured to the spike below the ground abutment plate prevent the spike from turning in situ, and the post tube and impact plate are cooperably square in section to prevent the tube from rotating on the spike. A sign carrying cross bar 24 is removably mounted in the open upper end of the post tube by a releasable spring detent strap 36 rigidly secured to a mounting tube 34.
