Our electric poultry netting is the ideal size for chickens, sheep and goats. To prevent sagging, all vertical lines are constructed from a semi-rigid fencing material. Get additional protection at the bottom of the fence thanks to the graduated spacing which starts at 2.5" high at the base of the fence and expands to 9" as you reach the top. Double step in posts are built into the netting so no additional staking is needed. 14/48/3.5 = 14 horizontal lines, 48" height, 3.5" vertical line spacing. A .25 joule low impendance fence charger is recommended for each roll of netting. (Example: 4 nets connected together requires 1 joule charger). Made In the USA.
