Polyester diamond braid rope offers the same strength and abrasion-resistant qualities as nylon diamond braid rope, but with less stretch. This makes it a good choice for a variety of uses: sailboat rigging, tug and barge tow lines, safety guide ropes, antennae guidelines, etc. The diamond pattern configuration creates a smooth surface that resists twisting, unraveling and overall general abrasions and also creates a rope that is a little more flat than typical braided constructions. Polyester rope is also highly resistant to mold, mildew, rot, gases, oils, alkalis and marine growth. It also offers superior resistance to heat and UV rays, so it won't weaken or yellow with exposure to sunlight.
