ABSTRACT:
An apparatus that facilitates the insertion of a stanchion into the ground. The apparatus comprises a first side including a plurality of connection apertures, a second side including a plurality of connection apertures, and at least one connector engaging the connection apertures to removably engage the first side to the second side. The first and second sides reposition the ground and substantially separate the stanchion from the ground during insertion. Additionally, the apparatus maintains the integrity of the hole into which the stanchion is placed during insertion of the stanchion into the ground. Preferably, the first and second sides define a substantially circular opening when engaged to one another. Additionally, each side includes a length and the connector substantially spans the length and vertically connects the first side to the second side along the length.
