Tubular webbing

**MidTNJohn** · 11-01-2014, 19:14

In the process of setting up a lightweight suspension.
Would replace Eno DN Rope end, Carabiners, Atlas Straps so I will be dropping a good bit of weight.

Looking at Huggers, Amsteel continuous (gathered end) and Amsteel Leads and Clips from www.hammockfan.com

I already have some climbing tubular webbing laying around.
Any reason not to use it other than that it is expensive?

I would just tie Fig Loops in the ends.
Was planning on 6'-7' finished length.

The main reasons to not use climbing webbing is that it's nylon and will stretch significantly, more so when wet so your suspension angle will change overnight adversely affecting the comfort of your hammock. It's also going to weigh a good bit more than an appropriate hammock webbing would...you said your looking to save weight. And it going to be overkill strength wise.

Roger That! Nylon webbing is used to take up the energy in a fall and stretches in that case. Especially when wet. It also is not waterproof and rots from the inside out.

Good point. Which brings up another. Nylon is degraded by UV substantially faster than polyester is. So the life span of straps from nylon webbing will be comprised faster with nylon. This of corse is more of a long term issue as is the rotting than the nightly stretching issue but still food for thought.

It will work fine. That tubular webbing is static and a tight weave. Very strong and good to 4500. You won't stretch it. I believe the rated stretch factor for a static tubular webbing is 3-4% rated at 4500 = something outrageous to make it stretch.

Climbing anchors don't absorb the dynamic energy in a fall. The Dynamic Climbing rope does that.
It is heavier than the stuff generally used in Hammock gear.

I've found ^^^ to be the case in my use if it. I made some huggers out of my extra climbing tubing and if it did stretch, I never noticed it. Also agree with the fact that you rope is intended to stretch, not the anchor.

Hmmmm

I have hung from it (harness) to know that it isn't dynamic.
I also know it is used extensively by Scuba divers so I wood be surprised to hear that it is rot prone or going to fall apart from UV

What I CAN imagine happening is that the Knots are cinching down under weight causing Sags.
I've used it Hunting...hanging all day from it and saw plenty of that but only noticed it on the first use.

Will have to experiment now....

Nylon webbing is static..?????

Show me some stats on your opinion, please.

Yeah, ahhh. Nylon is "Dynamic" (High stretch) Polyester is "Static" (low stretch)

Rsgary- that glossary is for their ropes they sell. Their dynamic ropes are designed different ie 2 part with an outer sheath. The static line is a single core right to the outside. I have a 65 meter dynamic line for climbing and a 70 meter static line for rappelling and cave drops. Regardless we are talking webbing not ropes.

I think where people get things mixed up is by thinking nylon stretches polyester doesn't. But that's not true. Even poly stretches. It depends on the fibers, tightness of the weave etc.

It's not an opinion it's fact. And it's been argued about here before.

I'll add the disadvantage to it is its heavy, thicker so it doesn't work well with buckles and is hard on sewing machines to sew double layers. Nice thing is that it does take well with knots like a water knot. You just won't easily take the knot out once it sets in.
