As a developer and manufacturer of webbings, the most important question that returns each time has always been, if my webbing is strong enough... 

Up until recently the most marking and generally most important indicator of strength and resistance of  a webbing has been the MBS. The Minimum Breaking Strength, that we can find on product pages and we use generally to determine the specific use of a webbing. 

After many years of research, calculations, tests and exchanges with other users that have researched similar topics, we can happily announce, that we came to a conclusion where the so called "C CAPACITY "can tell us much more about the resistance, than only knowing the kN of MBS of a webbing. 

From now on, all webbings at Slack Inov' and Spider Slacklines, will be presented online showing not only the MBS strength but also its measured C CAPACITY.

C CAPACITY quickly explained: 

• C CAPACITY is the indicator of HOW MUCH energy 1 Meter of a webbing can absorb before breakage 
• This is indicated in J/m (Joules per meter)
• The higher this indicator, the stronger a webbing will be to resist a shock load (leashfall or backupfall)
• Elasticity is taken in consideration to calculate the C CAPACITY 
• The global capacity of a setup is equal to the C CAPACITY of one single meter of webbing times the length of the line
• If the C CAPACITY is low, the webbing will be dangerous on short lines, you will need to increase the length of the line in order to increase its global capacity then make it safe.
  
  
  

ATTENTION Higher MBS is not always the indicator for a stronger, safer webbing:

High performance Dyneema webbings, which have usually very high MBS, but are significantly less stretchy and show less elasticity than f.e. a typical nylon freestyle webbing - the Dyneema webbing will be more fragile to high shock loads than the stretchy nylon webbing, which can absorb better the shock load through their elasticity.
