Customer Reviews for VEVOR Zip line Kits for Backyard 120FT, Zip Lines for Kid and Adult, Included Swing Seat, Zip Lines Brake, and Steel Trolley, Outdoor Playground Equipment
Must have a small come along to tighten the cable up first and if you are planning to put it up somewhere on level ground then one end must be very high and the other end be at least 9 ft due to the amount of slack. It will slack even more if you don't tighten it up first with a come along.
The kit comes with everything but the trees. We do not have tall enough trees so I did some research on you tube and found out you can use 2 2x12 , 12 foot long boards screwed together and bury 3-4 feet and you have posts for your zip line.
