I took two very rusty anchors from Trümmelbach and replaced them with new, stainless steel one.
After that I took the two old anchors (plate + Maillon Rapide) to our Mammut laboratory for breaking strength testing.
They were still ok and had a breaking strength of 23kN.
After 10 years or more in the water the breaking strength is still ok despite they do not look very trustworthy.


If someone else has old anchors used in canyons and would like to know the breaking strength; Just send them to me:
