Steel Line Lock In stock


A simple weblocker for the 2,5cm and 3cm webbing

The Line Lock is a webbing blocker.

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 our webbing. This is a basic item for a light and simple kit as the PrimitivKULRodeoRoller.

For shackles, length over 35m or thick webbing (Club S, McFlyMILF et Kill Bill), it's better to use the Fatlock

To go further

  • Over 35m, shackles and thick webbing (Club S, McFlyMILF et Kill Bill), we recommend the Fatlock
  • The line lock is to be used with carabiners, take care not to triload the carabiner. On trees over 1m50 of circonference the triloading can break your carabiner.
  • For longer lines or higher loads, we recommend the Sladlock Power (banana)

line lock setup


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
