It's a 48" electrifiable prefabricated fence. It arrives at your door as a complete roll with the posts already built into the mesh/fence.
White vertical plastic strings are "welded" to black and white electro-plastic horizontal strings. They are supported by .6" diameter white plastic PVC posts--which are spaced throughout the netting. Each post has a small, steel spike that is to be inserted into the ground for support.
Just attach a fence energizer and it's ready to keep poultry in and their predators out. One roll (164 ft) weighs only 24 lbs.
