Premier Enhanced 20" Electric Garden Net Fence, Green/Black, 9/20/3EG Installs in approximately 15 minutes. Effectively protects gardens and lawns. Repels rabbits, raccoons, skunks and small dogs when properly energized! FENCE MUST BE PROPERLY ENERGIZED TO BE EFFECTIVE. Energizer is not included. Recommend approximately .25 joule of energizer per roll of fence. Use only low or wide impedance intermittent pulse energizers. Warning! Do NOT use continuous current energizers with electric netting. For optimum results, we recommend using a Premier Solar or AC/DC energizer that fits your specific needs. Complete with PVC posts pre-fitted into fence at 10' intervals with 6" spike at bottom. Recommend using non-conductive support posts at corners and ends. See the Premier 20" FiberTuff posts on Amazon. Multiple rolls of net are easily clipped together by power clip at end of net.
