it's just the name of a really good brand hog wire.most is 52" high and will withstand most hogs.a roll is usuall 330' long so a roll should fence two feeders if done right.put a slight angle to the wire,about 6" to 8" out at the top with one strain of barbed wire on top. that way they can't climb it.just peg it at the botton and should be OK.
