摘要:
A safety pipe wrench includes a Y-shaped handle having a stem extending from a first end of the handle towards a second end of the handle. The stem bifurcates into a first arm and a second arm at a location between the first end and the second end of the handle. The first arm and the second arm extend to the second end of the handle. A slot is defined between the first arm and the second arm. A first gripping insert is mounted on the first arm. A nut is rotatably retained in the slot. A jaw has a shank terminating in a jaw head. The shank is movably engaged with the nut. A second gripping insert is mounted on the jaw head.
