Back-Ups and Tie-Off’s for Basic Slacklines
With both the primitive and the ratchet systems, it is important to back-up and tie-off your slackline in case of equipment failure. This is important because by doing this you can avoid situations such sending gear flying or cause injury to participants and bystanders in the event of an equipment failure. Fortunately, backing up both the primitive and ratchet systems is simple and effective.
To backup either tensioning system simply tie the loose tail of webbing around the tree and back onto itself, using a bowline knot. This method should keep hardware from flying through the air if anything at the anchor were to fail. If you do not have enough tail to pass around the tree, use rope or any other sufficiently strong material and tie back the hardware.
