How cool is this? Your very own Zipline! Testers were so excited, we had nonstop lines waiting for turns to try it out.. You’ll need 90 feet of space between two sturdy trees to start. Once you determine that your yard qualifies, you are just thirty minutes away from zipping down your very own line. Installation is very straightforward and easy. The quality is superb, featuring stainless steel cable along with galvanized clamps and hardware. The ride is smooth and the seat is light enough (even with a child aboard) to pull back for another run after the inevitable plea for “one more ride!” While kids are having a blast, theyre also playing outside, building strength, and sharing with others…hopefully! Parents told us they expected that any house with a zipline would instantly become the most popular house on the block.
