This is just a piece of felt with 4 pieces of wood. Long enough to wrap 360 degrees around a very small tree. I used them for zip lines in my backyard. I have trees that are 20 inches in diameter and they only cover the back of the tree at a 150 degree angle. You can easily make them yourself without much effort. I think that felt is not even needed. I would recommend simply cutting strips out of a piece of hardwood and being done with that.
