Ideal for applications requiring the flexibility of clamping on pipes from 3-1/4 inch to 20 inch diameter, these pipe clamp systems are flexible and easy-to-use. Swivelling v-blocks fit the contour of the pipe while the heavy-duty tension chains securely affix the clamps to the piece being drilled. The drilling position can be easily and safely adjusted.
