Abstract
A system has a pipe handling apparatus with an arm moving between a first position and a second position, a derrick having a window through which the pipe handling system delivers a pipe to a well head, and a header mounted in the window of the derrick. The header receives the arm of the pipe handling system when the arm is in the second position. An outside surface of the header suitably fits within the window of the derrick. An inside surface of the derrick suitably receives the arm. The inside surface resists an upward motion and a sideways motion of the arm. The header has a body that has a head and legs.
