Measuring 5.3 feet, this high-strength compression spring pairs with 3\/16 to 3\/8 inch cables to help manage speed and create a controlled stop. It’s built for safe operation on gentle slopes and supports riders up to 350 lb; for longer runs or heavier riders, you can add more springs to increase stopping power.\u003c\/p\u003e\n\u003cp\u003eDesigned with real-world use in mind, the system emphasizes predictable braking behavior over sudden halts.

As the rider approaches the braking zone, the spring compresses to absorb energy and slow the cable in a progressive way. This helps reduce abrupt transitions. If you have a longer line or a heavier rider, you can add additional springs to boost stopping power.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation and care\u003c\/h2\u003e\n\u003cp\u003eInstall in 1–2 minutes without tools—simply thread the zipline cable through the rubber ends and secure. Regularly inspect the spring and rubberized stoppers and replace as needed to maintain reliable performance.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the NTR Zipline Spring Brake compatible with different cable sizes?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
