The Crack System:

These exciting holds are screw on. This means they can be spaced to give various crack sizes from finger lock to hand and fist jam size. Team them together with some of our tiny footholds or even some of our mud pies to make a great crack climbing route. You can also use these holds for small ledges to generate mantle or rock-over moves.

Cautionary note: you MUST use all the screw holes when attaching these to a wall for live use.
