This tape is manufactured by a company that has been in the business for 70 years. There is only one thing to be considered when looking at Electric fence tapes, rope or twine - that is the conductivity (the ability to transmit electricity) of the material. An Elephant or horse will not be fenced in by plain rope or tape but apply an electric current and ANY terrestrial animal is capable of being contained. The lower the Ohms/metre is, the more electricity it will carry and deliver an effective sting. *The warranty offered on all the above ropes is limited to sunlight"s Ultra Violet degradation of the plastic material and does not cover mechanical damage by wind action, animal action, abrasion or damage by lightning strike.
