pasway Tandem Speed Dual Pulley Zip Line Trolley 30KN with Climbing Mountaineering Buckle Carabiner

Excellent quality!! Well built and sturdy!! I used them for my grandchildren's zip line. It was a big hit!!

Great product to have in your rope bag as you never know when you may need it. It can be used for more than just a zip line trolley as there is plenty of room between pulleys for double pulley use. The locking carabiner is of good quality as well.

270 foot zip line. Works amazingly well. Great bearings. Zero issues. Very well made. We use it often and love it.

Got this for my sons 20th bday, he hooked it up with a wire line across our field about 150ft, works perfect! Gone up to 180 lbs with no problems! We tried a diff one before but wouldnt go or got stuck alot, this one works great!

Works great for my 1/4" cable

I used this for a rope swing. It does the job nicely. Smooth operation and feels sturdy and safe. You’re going to need something else to stop you though. Trees are not as soft as you’d think.

Holding up great for my 138' outdoor zip line. After it rains it seems to collect a little bit of debris and dirt and slow down a bit. I just lubricate it with some silicone spray and it's great again.

I connected the pulley to an indoor steel cable and attached a baby bouncer to it and it works great. It's glides smoothly because of its weight, quality, and good ball berrings. Works 100 times better than any home depo pulley on the shelf. And dual or tandem pulleys work far better than a single pulley.
