The Curtain Slider (カーテンスライダー) is a First Stage obstacle that premiered in SASUKE 23 as the second obstacle, replacing the Circle Hammer.

Competitors must grab onto a curtain, and then used their momentum to slide the curtain onto a track to reach the landing platform.

Competitors that did not run fast enough into the obstacle would later fail to complete the obstacle, as the obstacle would stall midway through the track or it could move freely, causing competitors to get caught off guard.

While simple in design and function, the obstacle did good damage for the second obstacle.

However, the obstacle did prove very tricky when it was windy on the course, as was shown during Lee En-Chih's run when he had to push the obstacle like the Circle Hammer.

Despite its difficulty, it was only used for one tournament, and was replaced by the much easier X-Bridge in the next tournament.

The Curtain Slider appeared as the fifth obstacle on American Ninja Warrior 4 in Midwest region and American Ninja Warrior 6 in Miami.

In this version of the obstacle, there were three curtains (one large curtain sheet and two long curtains).

Competitors must grab the first curtain (the large one) and used their momentum to slide the curtain. Then, competitors must grab the next two long curtains, and swung those curtains to reach the landing platform to advance.

During American Ninja Warrior 6's Miami finals, the number of long curtains was reduced from two to just one (due to there were 42 competitors who completed the Miami qualifiers course and advanced to Miami finals).

This version of the Curtain Slider had eliminated much more competitors than the one used in SASUKE 23, as several competitors failed to generate enough momentum to slide the curtain, resulting them got stuck at the middle of the track and couldn't generate more momentum to slide the curtain and reach the long curtains.
