Ruggedness is increased through the use of a pressure-extruded, Core-Locked, or tightly bound, outer jacket that firmly binds all the fibers together so that the cable moves as a single, solid, rope-like unit. Cables can greatly exceed minimum industry standard requirements with flex resistance of thousands of cycles, crush resistance of 2200N/cm, the ability to withstand 1,000 impacts, and tensile load rating exceeding a ton.
