Webbing and knots

Brand new to the buzz, although I've been following and reading for several months.
I'm wondering about 1 inch tubular webbing and how it behaves with knots, specifically double fisherman's loop. I've got a long hank of the stuff, and I'm curious about putting it to use, possibly as a mid-line attachable removable redirect if I cinch it to some carabiners-I don't have a sewing machine or any splicing ability thus far.
I know I've read that it functions similarly to rope, only flattened, and that it can be used for a quick and dirty prussik loop, etc, but I haven't seen much about using it this way. I did find this old thread from '04

but I'm looking for some more feedback from you guys.
Would you climb off it in this application? Or does all its strength for life support come from being tied in an endless loop with a beer knot? It seems pretty solid when I tie it and dress it, no slippage or anything, but just wondering what you think.
Thanks in advance for any feedback, treebuzz fellows- what a resource!

Traditionally an overhand follow/water knot through is used to make a loop of webbing. Beer knot is just a little better..hehehhehe...clever name!

Nylon webbing can be used for friction hitches. but, nowadays there are much better fibers in use that have better performance characteristics.

It seems like you could use the webbing to make a sliding double fisherman's. In all of my reading about knots I can't remember that configuration being used.

When I make webbing loops I keep the tails about 4" long. To mark the tails for creep or slipping I make a line where the tail goes into the hitch/knot using a Sharpie. If the line disappears...there's slippage.

I couple of hand stitches on the end of the tail would do the same. If either layer of the webbing slips you'll end up with a pucker in material.

Welcome to TreeBuzz...nice to have you uncloaked!

Tom- thanks for the response-good idea about the markers to keep track of slippage.
To clarify I guess what I'm talking about is a scaffold knot (is this the same thing as double fisherman's loop?) to cinch either side of a length of the webbing to carabiners as opposed to the grapevine knot for making a loop. So the webbing isn't doubled over itself and girth hitched to the biners as in an endless loop, but just a single strap. Re-reading my post I can see that I didn't make this very clear.
I can post a picture in the morning to further clarify if need be.
Thanks
Jon

Ahhh...tying biner on using a Scaffold Hitch to choke it..???

A tied eye/eye is what you're after I think???

No reason that it won't work with a nominal strength loss of course.

If you're going to use any of the high mod webbing you MUST do your research first. Some of the fibers do NOT work well in a tied configuration.

I was wondering about using the dyneema loop runner that sherrill sells for a link between a lanyard adjuster and the saddle. Would it be alright to use as a prussik on say a 10mm OP lanyard. Not as the way for adjustment but to just avoid side loading the biner in srt.
 
Re: Webbing and knotsTrad

No comment on the application of Dyneema.

Do your research about using high mod fibers, some don't abide knots or heat very well.
