Bests & Worsts Reviews from Amazon

This is a well-made pulley with a good amount of line included. We're really pleased with it. We put it up for a 50' run between a deck and a large tree. I was concerned about our Montana windstorms and the potential for the tree to sway and the line be broken or pulled out. It was then that I realized that the pulleys have a feature built into them, if you add hardware, that is not shown or mentioned on the box. You can add tension springs easily. I purchased some much longer hook screws at a local hardware store to hang the pulleys on, then used the included hook screws for the springs (also purchased at the hardware store). It works great. The line is always taught, and there is an extra 6-8" of play in case it is ever needed. I've included a picture.
