Seated Zip Line Kit is one of the most exciting, smart cost-per-play products a family can own. As riders and watchers, both kids and adults are in on the action. Slackers Ziplines are so well made, such high quality – they are used for years. Comfort and safety are built right in with an easy-grip trolley to hold on to during the ride and a comfortable flyer seat. An adjustable bracket between the two – it’s a cinch to adjust to each rider’s height.
