Trsmima Heavy Duty Stainless Steel Zipline Spring Brake Extra Long 6.5 FT, Zipline Stopper, Kids Backyard Zip Line Spring Braking System/Stop/Stopper for 3/16 1/4 5/16 3/8 inch Wire

This spring is really rubbish and I wish I had spent double on a proper one. It barely slows down my 8 year old, yet alone my 14 year olds or me. Unless you have zipwire that moves at walking speed (when you don't really need a spring) then save you money and get a proper , thick, heavy duty one. I wish I had taken heed to the few lower started reviews

Stainless. top quality product that was available at the time of purchase. withstood years of use and seems it will hold well for at least a decade of ziplining

El resorte es muy débil, y no funciona como freno para tirolesa como se promociona (ni siquiera cuando la tiroles va muy lenta). Se conprome y llega demasiado fácilmente hasta su tope! No gasten su dinero en éste producto!

I got my 8 year old son a zipline for his birthday and he loves it. His 10 year old sister loves it too. I got the zipline from Hearthsong and although the zipline itself was great, the rubber stopper that came with it was horrible. Once you went down the zipline once the stopper would go all the way to the end and the next time you went down the zipline, there was a sudden stop. Huge safety hazard. We had to continually manually move that stopper after each ride to avoid anyone getting hurt. What a pain. Then I got this stopper and it works great. The coil retracts on impact and then extends back to its original length for the next ride. It slows the kids down nicely and no more manual intervention. Now they can play independently. I highly recommend this stopper with any zipline or similar ride device. In the video, you can see the stopper at the end of the ride.

Works as expected, we have used this for one season so far and we have been very pleased. Both children and adults have used this and it creates a gentle top and a nice spring back as well

Tyrolienne 3/8" sur 50 mètres. J avais déja acheté un modèle similaire ayant un bushing d acier qui est excellent. Mais celui ci sans bushing ne fait rétracte pas après compression. Non recommandé
