The obstacle consisted of two long chains, each with its own pulley mechanism, and the chains were positioned where each end of the chain was measured the same level apart.
- Competitors must transfer from the ladder separating it from the previous obstacle (the Jumping Ring) to the first chain.
- Then, they must swing out to transfer to the next chain.
- And finally, they must swing to get to the ladder, which was positioned after the second chain, as an intermediary to the next obstacle, the Rope Climb.
If the ends of the chain weren't grabbed at the same time, the end of the chain with the most weight distributed would lengthen while the other would shorten, forcing the competitor into the water. This was what happened to Hashimoto Kouji in the tournament, the only competitor to fail the obstacle of the three competitors to attempt it.
This obstacle almost took out eventual two-time champion Urushihara Yuuji, as he almost fell from transferring to the second ladder. Luckily, he was able to save himself from falling and would eventually clear the obstacle.
