Horses and other animals will be able to see this ½" highly visible polytape more easily than regular electric fence wire. Fi-Shock ½" Polytape has 656 feet (200 meters) of tape on a spool and 5 strands of electrical conductors. It has a breaking load of 150 lbs. This polytape is easier to install, repair and splice than regular wiring and it will not rust. Note: This is not designed to function under extreme tension and must be used in conjunction with a permanent fence.
