ABSTRACT:
A pump jack of a well is stopped when the polished rod clamp is elevated above the wellhead. A rod stand is secured around the polished rod encircling it. The rod stand is between the clamp and the wellhead top. The pump jack is lowered and then stopped when the clamp rests on the rod stand. After the well is serviced, the pump jack is raised and then stopped when the clamp is elevated above the rod stand. The rod stand is removed from the polished rod and the pump jack is started for normal operation. The rod stand is in the form of a pipe with a thick washer on each end, which has been split and hinged together.
