The amount of weight a dynamic climbing rope can hold depends on the rope diameter, rope length, and the type of knots being used. Naturally, thicker rope diameter and longer rope length typically hold more weight. All knots weaken rope strength by some amount.
When purchasing your dynamic climbing rope, look for the kN (kiloNewtons) number. This number is the maximum amount of weight each specific rope can hold. Here is a list of ARMBUY dynamic ropes and their kN impact force weight translated to pounds.
