Crampon locks let you have the best of both worlds. Dynamic when you want the ski crampon to be able to rotate up for eficiencey and locked for a static mode to get maximum grip. Can be; changed on the fly without getting out of bindings by just reaching down to engage and disengage. These should only be used with B & D crampons as most other crampons have a taper on the back that can damage the lock.
Crampon locks with the “Fritschi Groove” will still work with other bindings.
B & D Ski crampon locks are only approved for use on our crampons. They should not be used with the official Dynafit brand ski crampons or most any other. Their crampons have a taper on the back of the crampon which may cause our locks to fail.
