Safe, controlled detensioning for your SlackLine

The GIBBON Slow-Release System makes detensioning your SlackLine safer, smoother and more controlled. Designed to prevent the sudden release of stored energy, it helps protect your SlackLine, ratchet and, most importantly, you! Once installed, the system is always ready to use and allows you to release tension gradually, instead of all at once.

Ideal for SlackLines under higher tension, the Slow-Release System reduces wear on equipment and adds an extra layer of safety during takedown. Compatible with all GIBBON SlackLine sets and tricklines. Not suitable for longlines.

Use only as instructed. Always detension SlackLines slowly and with care. Do not use with long lines.

We offer a 2-year warranty on all GIBBON products, which covers manufacturing defects or failure caused by normal use.
