Premier PoultryNet Electric Fence, 48" H x 164'L, Single Spiked, WhitePremier 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. Keeps in poultry, sheep, goats, cattle and guard dogs. Keeps out deer, bear, raccoons, rabbits, foxes, coyotes, stray dogs and skunks. Single spiked posts that are woven into the netting fence at 10' intervals. Recommend using 48" FiberTuff posts (Item 208055 on Amazon) at ends and corners for additional support. MUST BE ENERGIZED TO BE EFFECTIVE. Energizer is not included. Recommend .25 joule of energizer per roll of netting. For optimum results, we recommend using a Premier Solar or AC/DC energizer that fits your specific needs. Use only low or wide impedance intermittent pulse energizers. Warning! Do NOT use continuous current energizers with electric netting.
