thin spectra webbing

[nacra533]

There is an aramid fiber (kevlar, nomex, technora) tape. Aramid has a high strength to weight ratio, but probably still heavier than spectra/dyneema.

These may be available for free on construction sites, electricians, telephone, power, cable installers or places where folks are pulling cable through conduit. In the utility industry, conduit is frequently purchased with the tape already installed in the conduit. Once the cable is pulled in, the tape goes in the trash.

Big down side is this stuff is lubricated and doesn't hold knots well at all. It also is SEVERELY derated by knotting it. See attached image from AD technologies for Bull Line

Nacra's links have an extra http//, remove that and they work. I found this pdf on the Muletape: http://www.neptco.com/website/neptco.nsf/attachments/muleknot/$file/muleknot.pdf

It shows how to tie a Mule knot in the stuff. It also warns not to lift or bind anything with it, for pulling only. But I'm intrigued, mostly because I work for Missouri's electric cooperatives and could probably get a ton of this for free. Anyone try it?

I have tried the 3500# 1" stuff. I also use it to tie things down in the truck or on the trailer. I've also stitched loops out of it for different things. The lubrication (dry - not oily) makes it easy to untie knots. It would work great for tree huggers, but I use ring buckles and a biner. I think the 3500# is a little heavier than the 1100# straps I am using currently. It's a little fuzzy, so it might pick up bark.

The "MuleKnot" looks like a variation of the angler's "bloodknot" with the exception that the muleknot is tied on the doubled over end or bight, instead of directy onto the end of the rope. If I remember correctly it was used when trying to retain a high percentage of the line's strength, without reducing it like some knots, also the multiple wraps can be tied with more wraps in slippery material (spectra, dyneema, amsteel, etc) Muletape just has a cool ring to it , as a name

It looks like you can pick up this material alot cheaper than the spectra tape marketed to climbers. I found several sizes on ebay. and a quick stop at a jobsite, or buried cable/fios install could yield it even cheaper (like for free)

Why do you want to use 1/2" webbing for tree straps? Seems to me that you would be negating the benefit (for the trees) of 1", 1-1/2" or 2" webbing's distribution of force. With 1/2" you are almost down to rope tree strap size.
