Don't let the size fool you, this is a strong rope. I used it to pull an ash tree that was 19 inches in diameter and 75 feet tall. This rope was very taut, and she held onto the tree and pulled it straight toward her. Failure would have been catastrophic because I was about 35 feet from the corner of my house. I am very happy with the strength of this rope and it is very easy to tie knots for its size and flexibility.
