Super Safe and Reliable

Top grade materials and high tech engineering, such as

  • aviation aluminum alloy AW7075-T651,
  • high grade steel AISI303 load bearing bolts,
  • custom taylored high friction rubber plates,
  • a 3 : 1 safety ratio of breaking load to working load,
  • a construction perfected through 8 years of R&D,

guarantees safety and reliability in almost any situation, and under almost all conceivable conditions.

“The LineGrip is the most revolutionary piece of gear for serious slackliners. I haven’t rigged without a LineGrip or TrickLineGrip in years. There’s just nothing better than a soft pointed highline or trickline.”

“Der Line Grip hat das Spannen von Slacklines nachhaltig revolutioniert und besonders seit der Kombination mit dem Hangover herkömmliche Flaschenzüge größtenteils überflüssig gemacht. Aber auch in Kombination mit einem Flaschenzug hat er mein Leben sehr bereichert. Ich benutze den Linegrip jedes Mal wenn ich Slacklinen gehe – also fast jeden Tag!”

“We used the tricklineGrip for the Forests Beasts project and it was the perfect tool for rigging as many lines as we needed with perfect tension. It is the perfect tool for trickhighlinig, so you can remove the pulleys from your system and enjoy the pure line!”

No need to fight for them, there’s plenty for everyone.

Function and safety ist paramount, but looks is key!

Its obvious, that our primary focus, when designing and developing the lineGrip, is on function and safety. Therefore the lineGrip radiates simplicity in form and design. 

In the first 7 years there was no fancy 3D sculpted surface, and no element that does not primarily serve a functional purpose.
This changed in December 2017. After functional perfection was achieved through the final detail - the Spring-Ball-Retainer - it was time to focus more on visual design.

The newest generation lineGrip - the G5 - features neat weight saving pockets and all-round beveled edges, instead of flat CNC-milled plates. Aside from the design aspect, this also creates a better haptic experience and further reduces the lineGrip's weight.
