The critical safety link between rider and zip line trolley. Engineered specifically for backyard and commercial zip line harnesses, the CTSC 3.9ft Adjustable Zipline Lanyard provides fail-safe positioning and redundant security on every ride. Featuring an ultra-durable high-tenacity nylon tubular webbing rated over 5,000 lbs breaking strength, a reinforced sewn eye loop, and a heavy-duty auto-locking alloy steel carabiner, this lanyard ensures riders remain centered, secure, and properly aligned directly beneath the trolley.
🛡️ Engineered Climbing-Grade Safety Features
- 5,000+ lbs Tensile Strength: Woven from heavy-duty high-tenacity nylon webbing, exceeding CE and OSHA recreational safety ratings for zipline tethering and personal positioning.
- Fail-Safe Auto-Locking Carabiner: Premium 25 kN (5,620 lbs) auto-twist lock alloy steel carabiner prevents accidental gate openings caused by rope flutter or vibration during high-speed rides.
- Smooth Length Adjustability up to 3.94ft (1.2m): Fast-adjust sliding buckle lets you dial in the exact drop distance between the trolley and harness, accommodating both toddlers and tall adult riders comfortably.
- Reinforced High-Visibility Eye Loop: Bright yellow color-coded eye loop with bar-tack safety stitching allows foolproof, quick inspection and connection to any harness ventral attachment point.
- Optimal Center-of-Gravity Alignment: Prevents uncomfortable rider swinging or tilting, keeping riders safely facing forward along the line of travel.

❓ Frequently Asked Questions
Q: How do I attach this lanyard to my harness and trolley?
A: Pass the sewn eye loop through your harness front attachment point or belay loop using a standard girth hitch (cow hitch). Clip the auto-locking carabiner directly into the bottom attachment eyelet of your zip line trolley, ensuring the gate twists shut and locks completely.
Q: Can both children and adults use the same lanyard?
A: Yes. The heavy-duty steel adjustment buckle lets you quickly shorten the lanyard for smaller children so their feet stay off the ground, or lengthen it for adults to maintain an ergonomic riding posture.
Q: Is this required if I already have a disc swing seat?
A: Yes! When using a safety harness in conjunction with or instead of a swing seat, this lanyard provides the critical tether connection ensuring the rider cannot fall even if they let go of the handles.
