To ascend ultrathin, gear-protected crack and face lines, Black Diamond Micro Stoppers are an essential tool. They make the head of each Micro Stopper with durable copper-infiltrated iron, giving it a tenacious bite while reducing shearing. A patented, swaged assembly allows us to use galvanized cables that are stronger and more flexible than traditional steel, making Micro Stoppers less prone to fraying after repeated use. Perfect for building that equalized rat's nest just before you punch it to the next distant placement. Micro Stopper Set: Micro Stoppers are available in a convenient set that includes the full size run of #1 to #6, neatly attached to an OvalWire biner. The Micro Stopper set is a great complement for any trad rack, old or new. Features: Ideal in ultrathin cracks, seams and fissures Copper-infiltrated iron provides great bite and durability Patented, swaged assembly increases strength American Alpine Institute Guideschoice
