Used it for a zip line for a 5 year old birthday party - worked well even with adults taking a turn ### ⭐⭐⭐⭐⭐ Way better than running into a tree trunk *by F***I on July 3, 2026* Works well. The children like the way it gently slows them down. ### ⭐⭐⭐⭐⭐ Good addition to zipline *by A***N on April 11, 2025* I had to add this compression spring to the kids' backyard zipline. One spring did not slow the kids down enough. I cannot fault spring #1 since the zipline is 100+ feet long and fairly steep so the kids fly down. They hit the deceleration zone quite fast. The extra spring and four (4) long bungies solved the problem. The kids were adamant they did not want to go slower and they actually relish the "bounce back" from the "arrest system." Both springs show no rust in our rather harsh environment. ## Frequently Bought Together - NTR Zipline Spring Brake,Brake Zip Line, Zip String 6.6FT Extra Long High-Strength Compression Stainless Zip Line Spring, Steel Ziplines Brake, Zipline Brake System/Stop/Stopper, Zipline Parts - Fusion Climb Z-Max - Fologtoo Zipline Seat for Kids and Adults, Zip Line Replacement Seat for Kids and Adults, Zip Line Accessories with Carabiner & Adjustable Nylon Rope --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/369388719-6-6ft-ziplines-brake](https://www.desertcart.no/products/369388719-6-6ft-ziplines-brake) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
