Review on Hi-Na Backyard Zipline Kit - 80ft, 100ft, 120ft - Zip Line Set for Kids Play with Seat and Handles - Backyard Ziplines for Kids - Premium 100ft Zip Line Kit - Outdoor Zip Line Play Set (80ft) by Phillip Johnson

This set contains everything you need to build your own zip line in the garden using two trees. When the box arrived it was quite heavy, but once I started removing the pieces I realized where the weight was coming from. The cables that wrap around the tree are thicker than the cable used to hold the green V wagon. This kit also includes tools to install all different size carriage nut bolts that allow you to open the carriage and place it on the wire. The turnbuckles use a different bolt size, but the tools also fit this size. The compression spring can also prevent me from getting the weight down to 190 pounds. The large turnbuckle allows for some slack in the cable, especially after doing a few test runs. The red disc can even support my weight but it's more for my 12 year old and his friends. This cable car became a local attraction and word spread quickly with parents asking where I bought this set!
