Set-Up a Slackline

Step 4 Set it up - Anchors

wrap the carpet around the tree, this will not only protect the tree, but make your line last longer.
then wrap one of your ten foot sections around the carpet and put one carabiner on the ends of the loop

do the same to the other side, but with two two carabiners on this side. make sure that BOTH carabiners go into both loops with the gates facing out

A worthwhile consideration on this setup: these carabiners are tri-loaded. In a shorter line as in this Instructable, that's probably not a problem, but consider other methods when rigging a longer line. Carabiners are rated to be loaded axially on their major axis (along the spine from end to end) and a tri-loaded 'biner will fail at a lower load. Again, probably not a problem here.

These are loaded in the same way you would rig an anchor for climbing. the biner is only being loaded at two points even though it is connected to three things.
