The Black Diamond Contact Clip is made from stainless steel, which means it does not rust like most other crampons, and snow and ice do not stick to the crampon so readily. Stainless steel is also more durable than carbon steel so the points of the spikes are more likely to stay sharp even if you spend some of the day scraping them over rocks rather than ice when traversing mixed ground comprised of rock, snow and ice. There are 10 points that are 3cm long, which allows them to easily provide grip on ice that is covered in snow. The two front points allow this crampon to provide grip when ascending slopes, while the four spikes that are rotated provide some braking power to prevent slipping on descent. Anti-balling plates are pre-attached to ensure snow does not cling to the base of the crampon. The standard Contact Clip is fitted to a boot using a front toe cradle and a rear heel clip, meaning it can only be fitted to boots that have a heel lip. However, it is also available with a heel strap for boots without a heel lip. The Black Diamond Contact Clip is rated as C1, meaning it can be used with semi-flexible 3-4 season boots and 4-season boots.
