Thanks for the suggestion for Grand Manner. However, that is for a cattle kraal. What I was looking for was the outer walls to make a large kraal to surround the Zulu huts thus making the entire kraal.
So, looking at the rest of the Grand Manner site, I found what I had seen before -- it's called "Black Thorn Straight (and curved) Coral". That was it, so thanks for pointing me in the right direction. Bob's your uncle!
