About Us

We are Veteran Crack Climbers

We have always been inspired by the beautiful and awesome power of cracks on the soaring walls of Yosemite, the red sandstone cliffs of Utah and Colorado, and all the amazing cracks we have experienced around the world!

Climbing Gyms have allowed our sport to explode in popularity. Climbers keep getting stronger and pushing the difficulty standards because of the accessible training opportunities our gyms provide. 

But what about Crack Climbing in Gyms?

Until now, crack climbs in gyms have been pretty limited due to the difficulty and expense of installing them. Gym cracks were permanent, and climbers unfamiliar with jam technique often struggled.

Jam Walls now offers Indoor Gyms a revolutionary and practical solution to crack climbing installations.
