The OK Brand bull panel is the heaviest panel we carry. Manufactured with galvanized before welding process, the 5 x 16 ft panel combines a 6 x 6 in spacing and a 1 ga galvanized wire. The 5 ft height reduces the likelihood of the animal going over the top while the heavy GA wire and 6 in spacing prevent them from going through the middle. The 16 ft lengths allow for even post placement at 8 ft, which increases the strength of the confinement area. This panel is built with one thing in mind, keeping your bull where you put him.
