Polished Rod Clamps

All Skinner Clamps are forged from high-grade, heat treated steel.Bolts are cadmium plated. Hinge pins are 4140 heat treated steel.The clamping surface of each Skinner clamp is bored and reamedto the exact size of the polished rod. Additionally, both endsare machine-squared with the hole to prevent eccentric loadingif the hanger bar is flat. The Skinner clamp exerts a 2:1 mechanicaladvantage in the ratio of distance from the center of the rod to thecenter of the bolt and from the center of the rod to the center of thepin. Contact areas are spaced to give maximum clamping effect.
