If you are going to order this product make sure you purchase in advance No Slash gloves and sleeves. I put my coils on the interior side of my wood fence,complete with warning signs. And when you are putting it up be careful not to stretch it! It will bounce off its nail,hook,whateverThis stuff is actually surprisingly easy to use and install. I moved it with the aid of a wheel barrow and a long handled paint roller handle.Imagine a giant dangerous Slinky.
