Understanding Slackline Gear Info

Searching for the right slackline gear can get confusing, considering the diversity of information you can find, explaining detailed facts like breaking strength, working load and safety coefficient. It’s important to clarify the fact, worldwide we have no existing governing standard for slacklines. All tests and standards have been developed over the years between slackliners and engineers of slackline related gear, by testing and working through important experiences.

BREAKING LOAD: This explains the minimum load under which any product can break 

WORKING LOAD (WLL or CMU): This explains a factor related to the breaking load divided by a certain safety factor. This safety factor is standardised at 5 for all lifting products ( f.e. a 1T WLL shackle will break at 5T). 

Generally, we have no existing standard, nor a compulsory safety coefficient within slacklining. Therefore, depending on the manufacturer, a safety coefficient can actually vary from 1-7, which means a seller could declare a working load equal to the breaking load.

Slack Inov’ Warranty concerning breaking strength transparency

Even if slacklining does not apply to any international norm in general,  in our SLACK INOV’ shop clear transparency about some of our standards are important to us. We decided therefore to mention only breaking strength in order to offer a standardized rating.This rating imposes f.e. a PPE standard (Personal Protective Equipment standard EN 362 or EN 12275). In terms of breaking strength SLACK INOV’s warranty stands for precaution and full transparency.

However certain products include a displayed working load limit. Those are products which can become subject to a certain mechanical fatigue, which means if the indicated working load will be exceeded, the product can become unusable far before their indicated breaking strength factor (f.e.).

As a conclusion and our recommendation, it’s best to pay great attention to indicated factors and values of a product, the same way we make sure to buy the correct carabiner, climbing anchors, harnesses and other, technical sports equipment for our specific needs.
