GM CLIMBING UIAA Certified Zipline Pulley Kit Speed Pulley/Trolley with Oval Carabiner Professional

It's a nice product. The pully will even glide across a cable that has a slight decline on its own. (no wind or anything) We're using ours for a kid's zip line. The only issue would be when the child dismounts. The pully can easily jump out of place on the cable when a child 'drops' off. (We are using very thin cable 1/4") The dramatic change in cable tension causes the cable to spring back up and the pulley has the freedom to move. What I explained is no fault of the pulley, it's designed with an open bottom. This is just something we will have to watch for.

Seems solid. We are using it for a zipline and it is fast.

This thing works like crazy. Love it. Seems well constructed and like it will hold up good... I will update if I have problems with it in the next couple of months

An excellent piece of hardware. Arrive on time and worked as expected. It was used for a homemade zip line (3/8") cable. Both adults and children were able to use it.

Love it. It's perfect. Zipline in the backyard, coolest family in the neighborhood!

Works great for my 1/4" 100' zip line. I'm planning to build a longer line and will probably use this trolley. Label says 13 mm rope diameter, slightly over 1/2", but works fine for my smaller line.

Replaced a general purpose stainless steel pulley on my sip line and had to totally change the elevations because this is SO FAST.

Great deal and quality for the price. Bought for backyard zip line (100' - 5/16" cable). Works well and seems like solid construction. I built this to support my weight (250 lbs) so my kids would have no problems. It glides well with the ball bearing rollers even for me.

Works brilliant just as described

Thank you it's great
