lineGrip approved webbing
Generally, every flat and tubular webbing type, made of plain, uncoated polyester (PES) or polyamid (PAD, Nylon), with 24-26 mm width, and a thickness of 1-5 mm, is approved for unrestricted use with the lineGrip.
For these kinds of webbing, you may rely upon the temp-load diagrams found here:
Tensioning of threaded tubular, stacked flat webbing and webbing made of high tech fibers (Dyneema, Aramid, etc.) with the lineGrip is possible to a limited extent only, and is therefore excluded specifically. Any use of these (not yet) approved webbing types, voids the manufacturers liability, and is therefore on your own risk and responsibility!
It is explicitly prohibited to use any webbing wider than 26mm with the lineGrip! Doing so, may lead to sudden and unexpected failure of the lineGrip due to excessive pressure on the levers, by the webbing trying to unfold to its full width. This might disrupt/destroy the lineGrip and hereby damage other equipment as well as severely injure any person near the lineGrip!
Special caution is to be observed, when using these types of webbing:
Coated webbing (i.e. Mantra MKII + Spidersilk with Resin-Coating)
Behaves critical when wet!
Slipping may occur sooner than with uncoated webbing. Increased caution is advised in combination with these webbings!
Webbing with Rubber-Printing (i.e. Gibbon Flowline)
Place lineGrip at positions with as little as possible rubber application!
Slippage of the lineGrip is unfortunately favored by the rubber applications. At what load slipping occurs is dependent upon different factors. Fact is, that it occurs a bit earlier than with plain, uncoated polyester webbings. Increased caution and attention is therefore advised in combination with this webbing!
Webbing made partially (hybrid) or fully of materials other than Polyester (PES) and Polyamid/Nylon (PA).
Slippage may occur prematurely, because it can not be assured, that the rubber coatings can generate adequate sticking friction on high-tech materials. Some examples:
• Dyneema-Webbing (Spectra) slips at ca. 7kN, even in the optimum temperature range
• Kevlar-Webbing (Aramid) even slips even sooner than Dyneema
• Vectran-Webbing with Resin-Coating (i.e. Spidersilk II): no slipping up to 15kN below 25°C, slipping from ca. 12kN at 30° C
We encourage to NOT use any high-tech webbing with the lineGrip as long as we did not approve it yet.
When using “non PES or PAD” webbing (on your own risk) a reliable backup with little slack is ever more important!
This will avoid injuries and damage to equipment once the lineGrip really does begin to slip.
When tensioning high-tech webbing with the lineGrip, please ensure to never exceed 5 kN in any case!
