Azarxis 30 kN Zipline Pulley 6700LBS Zip Line Tandem Dual Trolley Kit for Cable & Rope Heavy Duty for Rescue Climbing Hauling Backyard Zipline Mountaineering Rigging

High quality for the price. The machining isn't Petzl quality, but pretty good, and the pulleys turn easily and smoothly.

The media could not be loaded. Super easy to use! Day one of using it, seems like great quality ESPECIALLY for the price. I’m 260 and it’s rated for like…6,000 lbs or something…and it holds me, so I’d say it’s safe enough for my kids! lol super lightweight and smaller than I thought. Pretty quick too!

This is perfect! I can't wait to try it out. It's going to be so useful for me. I've been searching for something like this for ages. Glad I finally found it!

I use these on a cable to tether my shepherd who is a beast. I have to replace them one to two times a year because he is that active. With that being said these are the best that I have found.

It has a good working load strength. I only load less than 200# and travel 75 yards at modest speeds, but this one and the previous trolley work well.

Set up a zip line for the kids in the backyard this summer. I had an old pully sitting around with an aluminum wheel at first - it was chewed up by the cable pretty quickly.This one held up great through the summer with lots of use from the kids. It also seems a little faster than the first one we used.

Works great for what i used it for, zipline.

I set up a zip line in my backyard for my kids and the pulley trolley that it came with rubbed on the cable and didn't work very well, so I purchased this one and couldn't be happier! It's incredibly sturdy and has held kids and adults alike, and works every time exactly like it should! It's super lightweight and really flies down the cable fast because there is no friction of the cable on any of the components! I highly recommend!
