When using conventional Y-shape lanyards, there is a risk of the lanyard’s shock absorber being ‘short-circuited’ if the second lanyard arm is attached to a load-bearing component of the full body harness (e.g. an eyelet). As shown in the illustration, this ‘short-circuits’ the load-bearing carabiner arms, bypassing the shock absorber. After a short braking distance, the connector becomes static, resulting in a significantly higher risk of extremely serious injuries. In the worst case scenario, the high forces applied to the seam between the two arms as a result of the 180° misuse can cause the lanyard to tear at this point. This would result in a complete fall.
Thanks to an innovative design, the shock absorbers on all EDELRID lanyards with two arms are fully functional even in the event of 180° misuse. The patented design also works without restriction if the load-bearing arms are ‘short-circuited’. This means that the second lanyard arm can be attached to the load-bearing elements on the full body harness. All EDELRID products that are 180° fail-safe are labeled with a special symbol.
