It is fitted with a repeater gauge so that the driller can monitor tool joints as they go downhole, doubly assuring that all have the correct torque. Sometimes called an Iron RoughneckTM, after the manufacturer of one such wrench.

n: an hydraulic pressure operational assembly that go up and down the pipe and assure exactly torque.

a manufacturer of BOP and other well equipment. Also a common term for a section of the BOP stack that utilizes a large rubber “donut” that can seal on irregular surfaces or even on itself.
