## Questions & Answers

**Q: If the zipline brake is enough strong to stop riders safely?**
A: Dear Customer
Thanks for your question.
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%).

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.

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.

### ⭐⭐⭐⭐⭐ Good addition to zipline
*by A***N on 11 April 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.
