Zipline Trolley Kit with 25kN Carabiner Double Tandem Dual Pulley for 1/4 5/16 3/8 1/2 Cable for Backyard Zipline Climbing Rescue 30KN 6700LBS …

It works well on the 100ft zipline I built the kids. It was actually too fast compared to the other junk pulley we were using and I had to decrease the angle of the cable. I have it on 3/8 cable but its really made for a larger diameter cable. The only improvement I can see is there is too much space between the housing and the pulley which could potentially allow for the cable or rope to get stuck in between, especially on smaller diameter cables/ropes. My background is rock climbing and I climb daily working on trees and towers.

Ok

We needed something strong to tie out my military sons dog that we will be watching for a while. This trolley works great, very sturdy construction, feels very well made. Glides smooth and never gets stuck. It's an over kill I think but she will never break it.

Took some time to break in but it's works great now !nd it still has not broke lol.

I made a 100' zip line for the g-kids using 5/16" cable. This trolley works great and I highly recommend it and a making a zip line. I shouldv'e done this several years ago as the kids keep busy playing outside and having fun. The video games have taken a back seat.

This trolley has served us really well for our zip. Well enough that we bought a second one. Feels super sturdy on and off the cable. Bearings are super smooth. Easy operation and comes with the proper oval shape carabiner.

The quality of this pulley is excellent and has lasted the test of time in my backyard. A word of caution: I would not recommend if you plan to use a smaller size cable. The smaller cable sizes have a tendency to ride on the outer rim of the two pulley wheels, rather than in the track. I used 1/4 cable and the pulley has be adjusted for each use. I'm sure 1/2 inch cable would work great!

Doesn't roll smoothly
