NAXENZip Line Pulley Tandem Speed Dual Trolley with 25kN Carabiner

Works great and been using it for a while now. No problems at all seems to be made really well and durable.

This has worked great for my toddlers zip line swing / glides really fast and is relatively quite / would buy again.

Initially bought a standard pulley at harbour freight and quickly realized that wouldn’t work. Purchased this one and wow! It worked great on my steel cable zip line. It’s smooth and fast with no digging into the device itself (and I’m 220lb). Great thing is it is easily applied on/off without having to take the pulley apart or take down the line itself. Also works with rope.

I use this on our zip line that goes across our tank. Kids love it. It is outside all the time and has gone through Texas heat, little rain, and cool weather. It keeps on going. I bought a second one for a back up. Great product.

Works well for my backyard zipline,

Such a smooth pulley ! And has lasted a while on my kids zillion without anything messing up!

Bought this to replace what we had on our kids’ zip line. It’s faster and smoother and a nice improvement.

Application: zip line for children and adults. I’ve no experience with zip lines but some with mountaineering.I rigged this and a large pool noodle between two trees, the noodle to be the brake at one end. We have a chain-rigged child’s swing that I clipped into the included carabiner, and the system worked great. Nothing reminiscent of a Rambo movie, but a fun event for the children.
