The Sky Hooks is an obstacle, firstly introduced as the fourth obstacle on American Ninja Warrior 9 in San Antonio.
On this obstacle, competitors needed to hold on to a free-moving ring, which was rested on a cradle, and must swing into a cradle parallel to it. Then, they must repeat it for the next two rings and make a dismount to the landing platform to advance.
During San Antonio qualifiers, 25 competitors failed on this obstacle, including Kacy Catanzaro, who was an inch away from landing the ring into the last cradle.
During San Antonio finals, the second set of cradles was removed. As the result, only 3 competitors fell on this obstacle.
- The Sky Hooks was one of the eight obstacles that won the American Ninja Warrior: Obstacle Design Challenge, and was designed by Benjamin Tan, who was the youngest winner of the contest (at 7 years old).
- The function was similar to the second part of the Giant Ring Swing, in which competitors must swing the ring from one hook to the other.
