WNL Chuck

Developed in collaboration with World Ninja League and Monstro, the WNL Chuck eliminates the guesswork around bolt usage during competition. This redesigned chuck features an integrated bolt blocker that prevents athletes from grabbing the mounting hardware, keeping the focus on grip strength and proper technique.

The glossy bolt block forces competitors to move their grip down to the textured chuck body, maintaining the intended difficulty of the obstacle while ensuring fair and consistent judging. At 10" tall with a 1.5" textured grip, the WNL Chuck delivers the familiar feel of a classic chuck while introducing a competition-ready upgrade.
