Corroded Caving Carabiners and Hangers Break Tests
Hunter Campbell sent us some old corroded cave gear and we pulled it till it snapped. It's interesting how gear left inside of the earth will get so gnarly. I'd expect that for any non stainless steel, but the aluminum is what is the most interesting. There is also a surprising amount of home made gear in caves and it was nice to test some of that too.
Our Results: The Camp 22 rated for 21kN broke at 15kN. The blue carabiner rated for 21kN broke at 20kN. The omega rated for 31kN broke at 29kN. The other omegas broke at 26kN and 27kN. The Black Diamond carabiner rated for 24kN broke at 26kN. And the unknown 23kN carabiner broke at 25kN. The Petzl D Link rated at 15kN broke at 22kN
The homemade hangers broke crazy low. The normal looking one broke respectably at 23kN but the others broke at 7kN and 10kN which is way too low for a hanger. And the weird titanium one had such a small bolt that the bolt snapped at 10kN.
