For used nylon rope in good condition, what is the normal safe working load as a percentage of breaking strain?

Explanation:
Safe working load is the allowable load you should not exceed, chosen to provide a margin below the rope’s breaking strength. For nylon rope that has been used but is still in good condition, a common rule of thumb is about 25% of the breaking strength. This reflects a conservative safety factor of roughly four to one to account for wear, unknowns, and potential dynamic forces. So, even though the rope could theoretically withstand more, you limit loads to about a quarter of its breaking strength to help prevent sudden failure. Using a higher percentage, like 50% or 75%, would reduce safety margins, and 100% would push right up to the breaking point.
