Bolt-On Books (Boxed Set)

The Bolt-On Books (Boxed Set) by 111 Obstacles gives you a complete mix of grip options in one ready-to-install package. This bundle includes two straight Bolt-On Books and two angled Bolt-On Books, allowing you to create varied progressions and combinations without piecing together individual components. Use them mounted directly to a Ninja Pegboard or hang them with Nylon Straps (sold separately) to build floating grip challenges throughout your course.

With both straight and tapered options included, the Boxed Set makes it easy to scale difficulty for different athletes or training goals. Athletes can grab the bottom edges for more secure holds or, when mounted to the pegboard, use the top edges like cliffs for added challenge. All required mounting hardware is included, making this set a simple and flexible way to add multiple grip styles to your ninja setup.
