High quality cord. Strong and resistant to rot, mildew, abrasion, oil, grease, gasoline, marine growth and most chemicals. This construction is sometimes referred to as Diamond Braided and is strands of fiber tightly braided around a center core of parallel fibers forming a herringbone pattern in rope. Nylon's elasticity can absorb sudden shock loads that would break ropes of other fibers. Not spliceable. Natural silvery white color.
