Good addition to zipline
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.

Arrived very tangled
> Please consider different packaging for this item: the 6.5’ long spring arrived very tangled in a plastic bag. - I enjoy puzzles, so untangling it was somewhat satisfying. That being said, it did take about 15-20mins; so if you lack patience & do not want to untangle a 6.5’ stiff spring perhaps not for you. *Placing spring in a plastic sleeve would fix issue

Zip line stop
I bought this to install on my zip line that I put up for my grandchildren. It is not as strong as I thought it was going to be and that was a little disappointing. It works but I would not recommend for use on a zip line stop.
