This spring brake ,5.3ft length , can stop riders whose weight is within 350lb on the safe slope 2°to 3° of the ground（drop rang 3%-5%). **Q: Will this spring brake rust easily?** A: Dear customer, Thanks for your question. Our spring brake won't rust easily, because it is covered antirust oil. it will last as long as the cable it is on. **Q: Can it be installed on an existing zip line?** A: The existing zip line will have to be disconnected at the end where the brake coil is to be installed. The coil is fed over the end of the zip line cable before the cable is reconnected. **Q: What is the weight limit for this brake?** A: It need to consider the weight limit of your zip line firstly. For this sping brake, I think it can stop 350 pounds well. ## 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.dk/products/435404542-ntr-zipline-spring-brake-brake-zip-line-zip-string-6](https://www.desertcart.dk/products/435404542-ntr-zipline-spring-brake-brake-zip-line-zip-string-6) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-09-20*
