It is a kernmantle rope, so it has an interior core that provides tensile strength, surrounded by a woven exterior sheath designed for optimal strength, flexibility and durability. double kN rating + 10% and add 00 (two zeros) example: 40kN = 8800lbf Static Kernmantle Rope (Construction, tensile strength, what NFPA compliant) Nylon, 9000lbs, meets NFPA 1983 Prusik lines (Construction type, construction material, size (Diameter and length), Tensile Strength) Braid on braid, nylon, 8mm 5. ejgmuo fkmv skqof zwfm zfeqitbf wezotiz wslprl qolbn frxun hrpjyma
