Type F manual tong is especially designed for use on blitz rigs, portable masts, water well rigs, production workover rigs and other light rotary work. This light but rugged three-jaw tong handles pipe sizes from 2.3/8" through 10.3/4" by means of six interchaneable lug jaws. A plus feature is the 1.1/4" threaded-type hinge pins with slotted nuts that prevent the femate hinge from spreading and bending the pin. SK: Lucky_lakepetro
