❓ Frequently Asked Questions
Q: What distance between trees is recommended for this 120-foot kit?
A: It is ideal for trees spaced between 95 and 115 feet apart. The excess cable wraps around the starting tree and connects to the tensioning turnbuckle.
Q: How do the seat and safety belt work together?
A: The rider sits comfortably on the disc swing seat while the adjustable safety belt wraps around their waist and clips to the trolley's lower eyelet via the lanyard, providing redundant fall protection.
Q: What slope should be used for installation?
A: We recommend an average slope of 3% to 6% (about 4 to 7 feet of elevation drop across the 120ft span) for a smooth ride that stops comfortably at the 5.9ft spring brake.
