You won't believe how strong micro stoppers are! Climbing nuts tested in real rock

Climbing nuts tested to destruction in real rock. Watch us do our first tests of passive climbing protection in some bomber granite. We tested a Black Diamond Micro Stopper, some BD stoppers and an older Wild country nut. Let us know if you want to see more tests of passive climbing protection.

Check out this video where we broke nuts in the cam crusher adapter in our Slacksnap machine.
