what is a kn

kN is a metric measure of force. The 'k' means 1000 and the 'N' means Newtons. A Newton is equal to the amount of force required to give a mass of one kilogram an acceleration of one meter per second squared. The impact rating of 9.5kN means that it would take a force nearing a metric tonne to break the rope. In English, that means (very) roughly 1,900 pounds of straight downward force before this rope snaps. In other words, you'll be fine! Have fun!
