Fofana Ninja Slider Stainless Steel Slackline Pulley Red Turns Slackline to Zipper Rope and Obstacle Course Quick Installation in 2 Minutes for Zip Kit

Works great for a zip line

Grandkids love it

Great quality! We added this to a slack line kit we bought to bridge some extra space we had (and add some extra fun!). It’s nice quality and slides easily on the line. It held my husband and I well for some test slides :) Keep in mind you have to have an attachment for it (bar, ring, etc). This is just the slider itself. We just used one of the accessories from the kit we bought separately.

写真ではクオリティーが高いように思い購入しましたが、ベアリング部の品質が低いのが見た目でわかるほどで、強度に不安が残り、使用するか悩みます。

Missing of product not able to use it

I have purchased these before to replace on our ninja course and they are standard quality for these things which tend to wear out frequently. It is a decent price considering they have to be replaced for safety and function prob every other year and sometimes every year. They are easy to install and are a good fit as a replacement part. For safety reasons we don't try to push them beyond when they start feeling "slow" on the zipline and have been happy with the performance.
