Spare parts such as grapples choose advantage raw material, we forging and machining with CNC lathe, advanced heat treatment technology keeps the teeth hardness and internal toughness of the grapple. All these material and machining technology makes the cylinder and performance reliable. The overshot can catch a heavier fishing weight and longer service life.
