Zixar Système d'arrêt à Ressort, système de Frein/arrêt de Cour, pour câble de 3/16', 1/4', 5/16', 3/8'

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.

Paired 2 together for a 75yd zip line across a pond. Works great for the kids and does an awesome job assisting the adults in the slow down.

Great device! Personally tested by me! Because allowing children without testing is dangerous to their lives. When you touch the spring, you smoothly cling to it, it gradually changes its amplitude. You landed calmly and were not injured. The springs are reliable, sturdy. It has good nozzles. All this easily attaches to where you need it. I was tormented before, and now I enjoy a sporting vacation with my children! Thank you for not cheating.

Works for slower speeds/gradient, otherwise need additional brake. Ours was only17m long at 4degree slope and you would swing high when it fully compressed against the stop block. Eventually one of the rubber ends broke off but it still works.

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.
