Designed with versatility in mind, the Black Diamond Serac Clip Crampon is ideal for moderate climbs and glacial travel. This 12-point crampon bites into icy slopes and resists snowballing with dual ABS plates. The Serac's strong front points climb like a champ while the secondary points optimize stability. Use this crampon's clip attachment system with any pair of rigid-soled mountaineering boots that have 3/4-inch heel welts, and adjust the length easily with the curved link bars.
