We collect your line to process it in our workshop with our professional sewing machines.
ATTENTION: this product is only the home collection service and does not include stitching, which you will have to buy separately.
Service not available outside Europe.
If you are not happy with your purchase you can always return the product
Yes, by purchasing this product we collect your line from your home and you can purchase the sewing services you want from our sewing workshop.
If you do not want us to collect your line, you can send it directly to us at the warehouse address, but you must first notify us in order to receive approval from our technicians.
Generally speaking, your line must be in good condition before it can be processed.
Webbing that is exposed to the sun for a continuous period of 6 months or the equivalent of a maximum of 10 years from the time of purchase is considered to be at the end of its life. This service life of a webbing also varies according to other ageing agents such as contact with abrasive surfaces or chemicals, etc.
Accordingly, our technician will only carry out repairs if your webbing meets the following conditions:
If in doubt, before proceeding, write down the history of your webbing, with photographs to support it.
Use a carton of a suitable size for your line, with as little empty space as possible.
We repair all webbing that meets the above requirements.
Certainly! You could create a Frankenstein line by combining for example 3 different pieces of JOKER, ZAO and COSMIC to create a unique walking effect.
ATTENTION: it is not possible to join webbing cuts with different widths, e.g. 17 mm SKYDIAMOND with 25 mm JOKER.
Hi! Does the 50 meter longline kit come with webbing that has 2 sewn loops? Thanks! SIGMA is an element of statistical calculations, which allows to display a products’ guaranteed strength value throughout its manufacturing process. Therefore, it is related to product safety.
During the testing process, the greater the differences between the 10 recorded values, the higher turns out the sigma value.
For example, for 10 carabiners tested, their ten recorded values are usually different and not the exact same:
24,9 | 25,9 | 26,2 | 25,6 | 25,8 | 24,7 | 25,5 | 24,7 | 26,0 | 25,7 kN
So which value to take into account to display the MBS (Minimum Breaking Strength) value?
We first calculate the average:
(24,9 + 25,9 + 26,2 + 25,6 + 25,8 + 24,7 + 25,5 + 24,7 + 26,0 + 25,7) / 10 = 25,5 kN
We then calculate the variance:
24,9 - 25,5 = - 0,6 (-0,6)2 = 0,36
25,9 - 25,5 = - 0,4 ( 0,4)2 = 0,16
...and so on for the 10 measured values.
We add those 10 results:
0,36 + 0,16 + 0,49 + 0,01 + 0,09 + 0,64 + 0,064 + 0,25 + 0,04 = 2,68
And we create the average:
2,68 / 10 = 0,268
The variance is even to : 0,268
SIGMA (standard deviation) = square root of 0,268 = 0,5176
The maximum value displayed on the carabiner would be:
average of 10 carabiners = 25,5 kN
SIGMA = - 0,5176
____________________________
Displayed Value = 24,0724 kN
What you should know in particular about the 3 SIGMA safety margin?
We use the 3 SIGMA method to calculate the MBS.
We multiply the SIGMA for 3 (this is why it is called “3 SIGMA”) to boost the prudency in the MBS calculation.
Taking the 10 previous carabiners as an example:
The average of those 10 carabieners is 25,5kN
3 SIGMA (3 x 0,5176) = - 1,5528
_____________________________
Displayed value = 23,0472 kN
Our choice aims to maximize the safety of our users while using our products.
