    Hi, guys
    could you help me find some info on Swedish dynamic cable system (similar to Cobra)? I've found it once on a website with some sophisticated belts and full body harnesses...sorry for post in english, I hope you don't mind.

    Hi

    Im not sure, but you might find some info on www.skogma.se, but I couldnt find any there. But in a paper catalouge I have, the system is called GEFA.

    Good luck.

    are u sure they use spectra, seems like pollypro. i also thought spectra brakes down under uv light making it a poor choice for outdoor use.

    spectra

    that what they say, "spectra" and "dyneema" are the same : GEFA has a "dyneema" option (thanks again, Norwayclimber!). Treesave system has "spectra" 10/20 option and Cobra static - "dyneema". Ropes are made of "high molecular weight polyethylene", pardon my french. Lifespan of "cobra" dynamic system is 12 years, static...?

    Sorry about my absence, but I’ve now had time to do some more research on the Gefa system. (I left for my sisters wedding 5 min after I posted my first post, so I didn’t really have time to read all the stuff inn the catalogue.)

    From reading in my paper catalog the GEFA system is a system with dynamic ropes (not dyneema as this is a full static rope/webbing). This means you don’t have to add a dynamic component (like the rubber “dilldo” in the Cobra system) to the system. Just secure the ropes to the belts.

    The GEFA comes inn two different dynamic makes, one that stretches up to 5% and one that stretches up to 20%. The ropes are made to hold loads of 2, 4, 7 or 10 tons. There is an indicationthread woven inn that breaks if the rope is loaded more than 80% of its estimated loadcapacity.

    There is also one rope that is made of dyneema, but this one is static. It holds 14 tons, but stretches only 2%.

    As for the “skogma.se” page, if you write “gefa” in the slot up to the right, you’ll get up belts, ropes and all the other stuff.

    gefa

    hi, Norwayclimber and thanks for the info. looks like gefa system has many advantages over cobra...and really important ones, not only lack of this idiotic "black rubber cigar-shaped object and a little tube of soap". A

    Fresco in MN has a system called TreeGuard, or Guardian or something like that that is pretty reasonable. It is a hollowcore rope system and web tubing.

    One problem in the US with cordage and fabric is that the tariffs are pretty steep.

    This stuff used to be sold by "Svensk Trädvård AB", They no longer sell the stuff.
    The company is reconstructed and is a retailer of Germanybased company "Freeworker", i think.
    Saddles are sold nowdays by Cresto and the Treecabling is similar to Gefa...
