Doorknob Grasper (ドアノブグラスパー), called Doorknob Grasp in English broadcasts, was a Third Stage obstacle first introduced in SASUKE 25, replacing Rope Junction from the previous tournament. Directly succeeding Roulette Cylinder, it consisted of four stationary doorknobs, protruding from a wall. The competitors must transfer from the cylinder to the first doorknob, then make it all the way to the fourth doorknob. Each doorknob would have the tendency to rotate when the competitors grabbed on them, making it difficult to transfer from one doorknob to the other.

Only two competitors have failed at this obstacle, Brian Orosco in SASUKE 25 and Paul Kasemir in SASUKE 26, both interestingly being Americans. Possibly due to its high rate, this and Roulette Cylinder were replaced by the returning Arm Bike in SASUKE 27.
