Only aluminum stoppers to have notches allowing any size to be used back-to-back with any other size to make a completely solid placement whatever the width of the crack.

Set of 9 stoppers, each a different color to make them easy to spot on your harness. They range from the micro size 1 to the generous size 9, which means you will always be able to protect yourself thanks to their notched heads and extra flexible wire cables.

Their 'multi-corner' shape gives two placement possibilities per size, this together with the option of placing two at a time makes a total of 63 possible placement options!

A single set of stoppers you can take anywhere, from big limestone routes and the most impressive granite cracks (frozen or not).
