The Doorknob Grasper (ドアノブグラスパー), was introduced in SASUKE 25. Directly following the Roulette Cylinder, the Doorknob Grasper consists of four knobs protruding from a wall. The competitor must transfer from the cylinder to the first knob and so on. The knobs turn, making it difficult to transfer to the next knob unless turned to stay in place, wasting grip strength. Only two competitors (both Americans), Brian Orosco and Paul Kasemir, have failed this obstacle. It was removed after two tournaments, later making an appearance in the Stage Three on American Ninja Warrior 4 to American Ninja Warrior 7. On American Ninja Warrior 6 and 7, the obstacle was remade with 5 doorknobs, and is curved with the 3rd doorknob in the middle and 2 on each curve.
