Fatlock In stock


A simple weblocker for all the 2,5cm webbing

The Fatlock is a webbing locker.

It allows to set up the best length for your slacklining spot. You will be able to rig 10m out of your 25m webbing without making any knot.

No more knots. It is safer and quicker to set and remove. It fits perfectly in all of our webbing, even the thicker ones like Club S, McFlyMILF et Kill Bill) It is the best weblocker for 30m to 70m long lines.

The Fatlock works with the pin side of 12 and 14mm shackles, thanks to slots that center them on it. It is much more compatible than a classic linelock.

For a better overview of FatLock vs LineLock, please take a look at this article on our blog.

Montage Fatlock


Slacklining and particularly Highlining are sports having no legal framework or norms concerning the gear or the setup.

Consequently we cannot warranty our gear for Highlining.
Our products are tested by independent labs (Apave) and inside of our company via a process evolving with practice.

The results of those tests have no legal values, they aim to ensure the safety and comfort of using our equipment.

It is the responsibility of the slackliner to choose the right gear with adequate resistance and to have the necessary experience to adapt his installation to his practice.


  • Don't rig your slackline accross a path,a road or any crossing
  • Don't rig your slackline higher than 2m
  • Ride on a grassy or soft ground, without roots or rocks
  • Always backup your setup
  • Never use ratchets for highlining
  • Never use urban furniture as anchor point

This equipement is absolutely not made for highlining. Find more information on our website highline.fr
