Ring Loading!?!? We pulled apart a bowline loop tied into an alpine runner. Rock climbers tie closed loop bowlines in their slings to create lanyards for clipping into anchors and extending rappel devices. To learn more watch the full episode. What happens if you clip into the loop of the bowline instead of your belay loop? We tested alpine runners from Blue Ice, Black Diamond and Mammut. Blue Ice and Black Diamond exceeded 15 kN before they started sliping. Mammut only achieved 9 kN before began slipping.
