Are 12 Kn Carabiners Suitable For Climbing? All carabiners come with a kN, or kiloNewton rating engraved into the spine. If you have carabiners without a kN rating DO NOT use them for a life-load. A kiloNewton is equal to about 225 lbs., which is a force of gravity rating, not static weight or mass.
