Premier PoultryNet Electric Fence, 48" H x 164' L, Double Spiked, White Keeps in poultry, sheep, goats, cattle and guard dogs. Keeps out deer, bear, raccoons, rabbits, foxes, coyotes, stray dogs and skunks. It's a 48" electrifiable prefabricated fence. It arrives at your door as a complete roll with posts built into the mesh/fence. Very easy to set up. Takes approximately 15 minutes to set up. Highly conductive, only 35 ohms of resistance per 1,000 ft of fence. Important to perform routine vegetation maintenance to minimize grass/weed load on the fence and reduce energy drain. Double spiked posts for added stability. Double spikes work best in moist and/or soft soil. 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.
