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.

Great product

Perfect for zip line , this has slowed m and my kids down to a safe stop all summer and winter , easy to use and the length is correct as advertised, great quality and value for the cost .

Great add for a long zip line.

Works great. We have a 140’ zip line and used 2 of these to slow the kids down after 1 was an abrupt stop. Works perfect, kids can ride alone without me catching them now.

Everything I needed for a short zip line

This product is great and worked exactly as I needed it too. I have a short zip line (30’) for my four-year-old granddaughter. The coil spring action actually added to the zipline experience causing the child to suddenly whip towards the end point and swing back and forth to a gradual stop. Larger children or longer zip lines would find that the swing after hitting the spring brake was too short causing the rider to hit the pole/tree at the landing requiring an additional brake coil. In my case I got everything I wanted and needed. Simple to install also.

Helps a lot, adds gentler braking.

This brake helped a lot with the zipline I bought. We put it on after we had already installed it with the little brake that came with the kit. The 5 year old and 9 year old grand kids were not stopping well with the other brake, and this brake added some gentler braking. We just had to take the cable down, thread it through the spring brake, and then put it back up. I am hoping it won't rust-- if it doesn't, it will be pretty perfect. This brake was installed on a 250 lb. weight limit cable.
