The Claw™ pole clamps are designed to prevent the user from over-tightening the clamp screw and accidentally crushing or cracking the pole. The clamping function is limited so over-tightening cannot occur. Use these clamps with ball-and-socket cradles (5200-XX-050) and the ball-and-socket Link (5200-201) to make a custom combo. The clamps are designed to fit a pole diameter of 1.25 inches (32 mm).
