NTR Zipline Spring Brake Heavy Duty Stainless Steel Compression Spring Stopper For Kids Backyard Zip Line Cable Lines 6.6 Feet

The NTR Zipline Spring Brake provides a reliable and heavy-duty passive braking solution designed to bring outdoor adventures to a safe, gradual halt. Engineered specifically for backyard zip lines up to two hundred feet long, this extra-long six point six feet compression spring ensures a smooth stopping experience instead of a sudden, jarring impact. It is an ideal addition for families looking to secure their backyard setups for both children and adult riders weighing up to three hundred and fifty pounds. Crafted from premium, high-strength compression stainless steel, this spring brake exhibits superior resistance against various weather conditions, making it far more durable than standard bungee alternatives. It features a unique design where the high-rebound rubberized stoppers are firmly bonded through one-time injection molding, eliminating gaps and preventing damage from seasonal temperature changes. Compatible with multiple cable diameters ranging from three-sixteenths to three-eighths of an inch, it accommodates most standard setups. This essential safety component installs effortlessly in less than two minutes without requiring any tools—simply feed the cable through the hollow core before securing your line. Perfect for increasing backyard safety, it offers scalable stopping power by allowing multiple springs to be added in a series for longer or faster courses.
