A white prefabricated 164 ft fence that has 9 horizontal twines (8 conductive); is 35 inches tall installed, and has large white plastic vertical struts every 12 inches to reduce fence sag. White PVC posts are built into the mesh every 12.5 ft. PVC posts are .51 inch diameter with a 6″ single metal spike at the bottom to insert into the ground. The result, when energized properly, is a nearly impenetrable mesh to sheep, goats, coyotes and dogs. It’s low electrical resistance (only 38 ohms per 1,000 ft) is an important benefit for longer fences and/or fences with high weed contact. Must perform routine vegetation maintenance to minimize grass/weed load, as it will drain the energy from the fence if touching the live strands. Multiple rolls of netting may be connected together. Acceptable levels of electric conductivity on the fence can be difficult when low soil moisture conditions are present. If dry soil conditions occur frequently, a Pos/Neg (P/N) version of netting fence is strongly advised. 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 output energizers with electric netting. (Fi-Shock brand energizers which are sold as low impedance, continuous current output should NOT be used with electric nettng.) For optimum results, we recommend using a Premier Solar or AC/DC energizer that fits your specific needs. Premier’s energizers are found on Amazon. Recommend using non-conductive support posts at ends corners or major directional changes to maximize fences effectiveness. See Premier 35″ FiberTuff support posts (item 208053) also sold on Amazon. Precautions: Electric fence is a pain barrier, not a physical barrier. A common mistake is not electrifying it. Animals may escape or become entangled (and may die). On a % basis, entanglement is very rare, but it can and does occur.
