What Do kN Ratings Actually Mean?

kN Ratings. kN ratings are shown on all your climbing gear: nuts, cams, slings and carabiners . kN stands for kilo Newtons. 1kN is about 100kg 220lbs for the Americans . So this nut will hold around 900kg. This is Nelly. She weighs 850kg, so the 9kN nut would hold her weight – just. But if Nelly climbed above the nut and then fell, she would
