Braided Nylon Cord 10 ft. (3 m) 150+ lb. (68+ kg) test, won't unravel, shelter building, repairs and much more This braided nylon line is rated a minimum 150 lb. (68 kg) test. While some of the line we tested went as high as 205 lb. (93 kg) test, we chose to list the lower number to be on the conservative side in case suppliers change. Poly line is cheaper, but not nearly as strong. Twisted line is cheaper, but unravels badly when cut and isn’t as strong.
