Rerun Trolley Return System

We've updated the Rerun Trolley Return to solve some of the common issues our customers encountered with the first edition. We will continue to sell the first edition Rerun at a discount until supplies last.   You've built your dream backyard zip line setup, but now you've got to walk your trolley back up to the top of your zip line after each ride. Trust us, we don't like it either.   We've finally designed a solution - the Rerun. (Patent pending)   The Rerun is designed with a pulley system that uses a counterweight to bring your trolley automatically back up to the top of your zip line after each ride. The Rerun works with zip lines up to 300' in length. Refer to this chart to determine how much vertical space the counterweight will need, based on your zip line's length. The Rerun is compatible with zip lines that have a 6% slope or less. Intended for use with a seat or harness. We don't recommend you use the Rerun with a handlebar trolley only, a Brakehawk/Trolley combo (without a seat), or in situations where the rider is dropping off of the trolley into water as the return line can tangle. Check out the Boomerang Trolley if you want to drop into water. The Rerun has been entirely developed in-house, and is produced using 3D printed parts. The Rerun is not without its limitations - so please be sure to review our distance chart to determine if this product will be right for your installation. If you purchase this product and it does not work for your zip line setup, we will be happy to accept a return for a full refund.   Want to see how it works?
