Directly following the Roulette Cylinder, the Doorknob Grasper consisted of four doorknobs, protruding from a wall. The competitors must transfer from the cylinder to the first doorknob and so on. Each of the doorknobs would rotate when the competitors grabbed on them, making it difficult to transfer from one doorknob to the other.
American Ninja Warrior Appearances
The Doorknob Grasper appeared as the second obstacle in Stage Three from American Ninja Warrior 4 to American Ninja Warrior 7, also as the second obstacle of Stage Three. On American Ninja Warrior 4 and American Ninja Warrior 5, the obstacle had a similar specification from SASUKE version.
On American Ninja Warrior 6 and American Ninja Warrior 7, the obstacle was modified with 5 doorknobs, and the doorknobs were positioned in an inverted "V" pattern. The first three doorknobs were being stationary, and the last two doorknobs were prone to spin. Also the gap to cross between each doorknob was 2.5 feet.
Just like in SASUKE, the Doorknob Grasper directly preceded an obstacle with no rest:
- On American Ninja Warrior 4 and American Ninja Warrior 5, the Doorknob Grasper was preceded by the Roulette Cylinder.
- On American Ninja Warrior 6, the obstacle was preceded by the Cannonball Incline.
- While on American Ninja Warrior 7, it was preceded by the Psycho Chainsaw.
During its overall appearances on American Ninja Warrior, just like in SASUKE, only 2 competitors have failed at this obstacle (Travis Weinand on American Ninja Warrior 5 and Kawaguchi Tomohiro during USA vs. The World 2).
