Polished Rod Clamps
Our polished rod clamps are forged from high-grade heat-treated steel, and they can hold the heaviest rod string in rod pump and PC pump applications. The clamping surface is drilled and reamed to the exact size of the polished rod. In addition, the contact areas are spaced apart to provide maximum clamping effect. If the hanger bar is flat, both ends are squared with the hole to prevent eccentric loads.Specifications
