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 500' 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.

FAQ
How do I measure elevation change in my backyard?
Please refer to the manual that comes with your kit for specific installation instructions.
Stand at the end tree and hold a 4 FT Carpenter’s Level like a rifle. Holding one end up to your eye, point the opposite end at the base of the starting tree, right where the dirt and tree meet. Make sure the bubble is between the two hashes indicating level (crouch down if your yard has a minimal slope or climb a ladder if your yard has lots of slope).
Once you have the level aiming at the base of the starting tree, measure from the Carpenter’s Level down to the ground. This measurement is your natural elevation change.

How do I figure out the slope for my zip line?
Please refer to the manual that comes with your kit for specific installation instructions.
The slope determines the speed of the zip line. Essentially this is the angle you set the cable at between the two trees. The slope is calculated by multiplying the distance between your trees times .03 or 3%.
More details on Slope can be found in the Zip Line Gear handbook included with your purchase. You can also view a digital version of the “Cable Slope & Sag” right here. We recommend finding a landscape with a natural slope of 3% to 6%, This is a 3’ - 6’ foot drop per 100’ feet.
For zip lines that will NOT utilize a Bungee Brake System, (a Stop Block is NOT a braking system) the maximum allowable slope is 3%. For zip line setups that include a Bungee Brake, the maximum allowable slope is 6%.
!!WARNING!! Zip line must never exceed 6% (6’ foot drop per 100’ feet) riding slope. High speed collision with end point may cause injury or death.
I don't have trees. Can I use posts?
Yes you can, but you need to carefully read the instructions for how to select, and install posts in the Backyard Zip Lines handbook included with your purchase. Alternatively, you can review the information in the digital version of our handbook right here.
If you are in any doubt as to how to properly select and install a wood post, please do not hesitate to contact us at 888-476-3701.
