Abstract
A pull cap is positioned about the exposed end of a probe rod and engages a pulling device to remove the probe rod from the ground. The pull cap has a first body section with a first concave surface disposed adjacent one end of the first section and for engaging the exposed end of the rod. The first body section also has a first channel on its outer surface adjacent the other end of the first section. A second body section has a second concave surface disposed adjacent one end of the second section and for engaging the exposed end of the rod. The second body section also has a second channel on its outer surface adjacent the other end of the second section. A hinge arrangement is disposed on both the first and second sections adjacent the other ends of the first and second sections. The hinge arrangement hinges the first and second sections together so that the pull cap has an open position and a closed position. The first and second concave surfaces engage the exposed end of the probe rod when the pull cap is in its closed position so that the pull cap can be used to remove the probe rod from the ground. An elastic member is positioned in the first and second channels and biases the pull cap into its closed position.
