Please Note - When using this kit at high tension tricklining, it is STRONGLY recommended to use slings, shackles and a backup rope. Using a girth hitch at high tensions is not sufficient enough to handle the extreme forces put on a slackline when tricklining, and can result in damage to the products, serious injury or worse.

The best place to set up your slackline will be between two trees, which must be mature and at least 24 inches around. Use of the included tree protection is HIGHLY encouraged on all Slackline Industries products. It will not only protect what you use as anchors (i.e. trees and posts), but it will prolong the life of your gear. It is also the right thing to do.
