Premier ElectroStop Goat & Sheep Electric Fence, 42" H x 164' L, Double Spike, WhitePremier Netting is 164' per roll. Vertical plastic struts reduce fence sagging between fence posts. Multiple rolls of netting may be connected together. Works well in containing sheep, goats and guard dogs, while repelling coyotes, stray dogs and bears. Much lower electrical resistance than most electric netting fence due to the tinned copper super conductor. ElectroStop has only 38 ohms of resistance versus 380 ohms for normal stainless steel conductor electric net fence. Important to perform routine vegetation maintenance to minimize grass/weed load on the fence and reduce energy drain. Very easy to setup and move. Takes approximately 10 minutes to setup a roll of netting. 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.
