How to Set Up TWO Slacklines Using ONE Piece of Webbing

Have you ever found yourself wanting to set up more slacklines than you have webbing for? With a longer slackline, and some additional gear, you can transform one piece of webbing into multiple slacklines. The feasibility of this trick depends on the length of your webbing and the distance between the trees available to you.

Why Consider this Setup?

Imagine heading out for a slacklining session, and a friend joins you wanting to practice but doesn’t have their slackline. Or, perhaps you’re conducting a workshop with short lines and need to set up more lines than you have webbing for. Following this method will allow you to utilize the excess webbing at the end (the tail) to create additional lines.

Here’s how:

Determine the Gear Required

You will need your slackline webbing plus these items per desired slackline setup.
this spread sheet to calculate your gear requirements. 

QT Item Notes
Locking or non-locking
Minus 1
Subtract One per shared tree (if the lines are going to be set at a similar height)
For our example, where we set two lines using one piece of webbing with one shared tree, we will need:
  • 1 slackline webbing
  • 4 anchors (2 lines x 2 anchors)
  • 6 carabiners (2 lines x 3 carabiners)
  • 3 line locks ((2 lines x 2 line locks) – 1)
  • 3 pieces of tree protection ((2 lines x 2 pieces of tree pro) – 1 shared tree)

Picking Trees (or Anchors Points)

Choose trees close enough so the webbing can span the distance. A handy method to ensure sufficient webbing is to lay it loosely on the ground, tracing the intended slacklines’ path. Don’t forget to allocate extra webbing for tensioning.

Place Your Tree Protection

If your lines are similar in length and height, you can share the tree protection. In our example, we’ll use three pieces for two similarly-heighted lines.

Installing Anchors and Carabiners

Both the starting and ending trees require one anchor each, while the middle tree needs two. Attach a carabiner to each anchor. You could save on gear by girth-hitching the slackline webbing around the first tree, but this limits available webbing for tensioning and later practice.

Setting Your First Line

Establish the initial slackline using the standard primitive system. Be conservative with the tensioning to avoid using excess webbing. Pre-set and re-tension the line—using methods like walking or kneeling on it—to help the webbing settle. Remove any slack before proceeding.

Setting Your Second Line

  • Far Tree: Wrap the excess webbing around the middle tree’s outer side (the larger angle) to the last tree. Secure the webbing using a line lock, leaving a tail of about two hand-widths. Ensure the webbing lies flat as you head back to the middle tree.

  • Middle Tree: Set up the tensioning system. Tuck away any extra webbing at the anchor for a tidy appearance.

Additional Notes

You can repeat this process as long as your webbing and gear allow. While this method is especially useful with the 108-foot e-line slackline, it’s also suitable for a 50-foot variant or other lengthy webbings.

We hope this guide is beneficial! Tricks like this add fun and optimize the gear we have. Slacklining isn’t only about balance—it’s about innovation and creativity too.
