This deer fence wire, recommended for horse fencing, is made of a high density polymer that has a breaking strength of 1,250 pounds per line (in a horse fence consisting of 5 lines, the containment strength of the fence would be more than 6,000 pounds). This polymer contains UV-stabilizers that prevent damage from the sun and extreme weather conditions, and since it is monofilament, it will never rust or corrode. This material has also proven resistant to the potentially damaging affects of pesticides, herbicides, acids, rot, and seawater. Throughout time, this 8 ga monofilament wire will never sag--with 24% elongation, even after bearing weight, it will return to its original size. This 8 gauge monofilament wire contains 8 gauge wire roll is 2,000 feet.
