Video description: Cracks A, B, C, and D are stacked on a 17.5' wall and being climbed by a sport climber. This crack setup climbs at a 5.10.
You can also purchase them individually as stand-alone rails.
Buckle up for this description because the options are endless. For starters, you can butt Sections A to B, resulting in a tight seamline feeling 5.10/5.11 on a vertical wall. Yes, you can cheat the hold and face-climb it, but that's not the point. Options to space the cracks further away from each other to practice specific jams and learn how to place natural gear is the point.
Crack Sections A and B offer myriad choices for fingers, hands, and gear placements. Each side has very little incut.
Where you can get a lot more possibilities is to set the cracks offset from one another, parallel, in a "V" orientation, and even horizontally to practice Tri-cam placements.
So whether you want to learn how to place gear or practice jams, this set has an answer for you.

Crack Sections A and B have a primarily neutral incut.
Crack Sections C and D have one side slopey and the other as an incut jug.
