Eliminate harsh stops and protect your riders with the CTSC 5.9ft Stainless Steel Zipline Spring Brake. Engineered specifically for backyard and commercial zip line courses, this extended 5.9-foot compression spring creates a gradual, soft-stop deceleration zone that cuts impact force by over 70% compared to basic friction stops or short 4ft springs. Built from heavy-gauge 304 stainless steel with impact-dampening nylon end caps, it cushions high-speed momentum smoothly for riders up to 350 lbs without metal-on-cable abrasion.
🛡️ Engineered Soft-Stop Safety & Durability Features
- Optimized 5.9ft Deceleration Zone: Nearly 6 feet of progressive coil compression absorbs kinetic energy gradually, preventing abrupt jolts and protecting riders' joints and spines.
- Industrial 304 Stainless Steel: Weatherproof stainless construction resists rust, rain, snow, salt air, and intense UV exposure for years of reliable outdoor service.
- Dual Impact-Absorbing Nylon End Caps: Heavy-duty nylon stoppers cushion trolley impact and eliminate metal-on-metal friction, preventing cable fraying and extending cable lifespan.
- Universal Cable Compatibility: Effortlessly slides onto all standard zip line cable sizes: 3/16" (5mm), 1/4" (6mm), 5/16" (8mm), and 3/8" (10mm).
- Automatic Hands-Free Braking: Passive mechanical compression requires zero rider intervention—riders do not need to pull levers, ropes, or friction pads to come to a complete stop.
- Heavy-Duty 350 lbs Rider Capacity: High-rebound coil wire supports growing kids, teenagers, and adult riders without coil fatigue or deformation.
- Meets CE & ASTM Standards: Rigorously tested to international playground and backyard adventure toy safety standards.

❓ Frequently Asked Questions
Q: Where should the spring brake be placed on my cable?
A: Slide the spring brake onto your main cable before securing your finish tree clamp or turnbuckle. Position it roughly 10 to 15 feet before the ending tree anchor so the rider comes to a complete rest safely away from the tree trunk.
Q: Will this spring brake work with non-CTSC zip lines?
A: Yes! Its internal diameter fits all standard galvanized steel aircraft cables from 3/16" up to 3/8", making it compatible with virtually any residential or commercial zip line system.
Q: Does the spring brake require any tools to install?
A: No tools are required. You simply thread the cable through the center of the spring brake during initial cable rigging.
