How strong are bolts in a climbing gym. I have always wondered this while I'm falling through the air only being caught.... by plywood??? We found out it is all secured into the super structure of the metal framing behind the climbing gym wall. Then it was fun to take some 11ply Birch Plywood and break test it. Shear broke at 26kn or 5800lbf and in tension 12kn or 2700lbf. It may not be that strong if 6kn was cyclically loaded on it or even a shock load but that is what we got in a single slow pull tests. Thank you Clint and Gary (@clintrycolwell and @garymattos) for showing us behind the wall.
