❓ Frequently Asked Questions
Q: Can adults ride this 120ft zip line?
A: Yes! The galvanized aircraft-grade steel cable and dual-bearing steel trolley are rated to support riders up to 250 lbs (113 kg).
Q: What distance between trees do I need for a 120ft kit?
A: We recommend a distance of roughly 100 to 110 feet between your anchor trees. This reserves 10 to 15 feet of cable for tree wrapping, clamps, and turnbuckle tensioning.
Q: What slope is recommended for safe operation?
A: We recommend an average slope of 6% to 8% (about 2 to 3 feet of vertical drop for every 50 to 60 feet of run). This delivers an exciting glide while allowing the 5.9ft stainless steel spring brake to stop the rider smoothly.
Q: What tree diameter is required?
A: Always choose healthy, mature trees (such as oak, pine, or maple) with a minimum trunk diameter of 12 inches (30 cm) at the mounting height.
