PoultryNet is an electrifiable, prefabricated portable mesh that arrives at your door as a complete fence. Posts are preinstalled at set intervals. Multiple rolls may be connected together. EASY INSTALLATION Netting is quick and simple to move. Even for new users, it takes less than 10 minutes to go from out-of-the-box netting to installed fence. KEEPS IN chickens, ducks, geese and other poultry while keeping their ground-based predators out. Recommended for containing heavy, non-flying birds. SINGLE SPIKE POSTS that are woven into the netting fence at 12' intervals. Recommend using 42" FiberTuff posts (Item 208054 on Amazon) at ends and corners for additional support. MUST BE ENERGIZED TO BE EFFECTIVE. Energizer is not included. Warning! Do NOT use continuous current energizers with electric netting. A highly visible electrifiable prefabricated fence. It arrives at your door as a complete roll with the posts already built into the mesh/fence. White vertical strings are "welded" to black and white electro-plastic horizontal string. Vertical strings are spaced 3 inches apart and horizontal strings are spaced closer at the bottom of the fence to repel smaller predators. Horizontal spacing from bottom to top of fence is 2", 2", 2", 2", 4" 4", 4, 4", 4", 6", 8". Fence is supported by .6 inch diameter white plastic PVC posts--which are spaced at 12 ft. intervals throughout the netting. Each post has a 6" single spiked steel stake at the bottom to be inserted into the ground for support. Much more highly conductive than other netting fences due to a tinned copper super conductor woven into the fence along with the stainless steel conductors. Only 35 ohms of resistance per 1,000', as compared to 380 ohms of resistance on a net fence with only stainless steel conductors. Just attach a fence energizer and it's ready to keep your animals in and their predators out. 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 currrent energizers with electric netting. For optimum results, we recommend using a Solar or AC/DC energizer that fits your specific needs. Important to perform routine vegetation maintenance to minimize grass/weed load on the fence and reduce energy drain. Also recommend using non-conductive support posts at ends, corners and major directional changes.
