Description:
The gripping block can be removed, rotated and re-ground. The chain has side flanges to protect the rivets that connect the links. The size adjusts by the position of the clevis at the end of the chain. The handle is a section of pipe connected to the head by a coupling which facilitates different handle lengths depending specific work requirements.
