ISA:21 Highline Systems What is a highline? The ISA:21 Highline Systems Standard is a formal engineering definition and description of what a highline is and what the various components it consists of are. In addition to that, it also defines the forces that are acting upon the webbing, anchors and the highliner. In essence, it is a lot of fancy words, but it allows our partners and testing laboratories to communicate more effectively. Download Highline System Standard 21:2019 On one hand this standard provides a framework for highliners as well as slackline [...]
New World Record in Switzerland!

Instead, 4 very unslack, static cables and 26 hammocks paint the scene. These 26 hammocks rigged as a caravan [...]
Webbing slippage warning in Weblocks. We have identified the mechanism responsible for webbing slippage in webbing lockers (weblocks). During a test on a hydraulic cyclic testing machine, we found webbing to move through the weblock with every stretch and release cycle. We observed this micro-slippage of the webbing within the weblock. Read Full Report - Webbing slippage warning in weblocks The webbing was installed in single wrap without a tie-off so we could witness webbing slippage, webbing tailwalk, and a complete failure of the webbing locking mechanism first hand. The Solution [...]
