Versatile thin crack pro, trapezoidal Micro Stoppers feature a subtle curve on their longest face for maintaining utility in near-parallel cracks while still catching on crystals and irregularities. You can also turn them 90° for a broad flare. Their patented swaging system increases cable durability.

Excellent for building that equalised rat's nest just before you punch it to the next distant placement, Micro Stoppers' patented, swagged assembly uses galvanised cables that are stronger and more flexible than silver soldered stainless steel. Bottom line: they're less prone to fraying after repeated use. U.S. PATENT NO. 5,794,914.

Set #1-#6 Micro Stoppers are available in a convenient set that includes the full size run of #1 to #6, neatly attached to an Oval Wire 'biner
