The strength of strap friction on trees

[Rain Man]

It's not the number of wraps, it's the amount of surface of strap to tree bark.

Where I camp, the trees can often reach five feet in diameter at the base. That means thirty feet of strap just to go around the circumference of both trees ONCE. I can't imagine carrying enough strap to wrap several times. Just three wraps leaving a tiny 5' tail would require 100' of strap!

I have hung by wrapping at tree strap around a tree and not attaching it any other way (no hardware, no loop, no knot). Held just fine.

BTW, I never hang any excess strap or cord on the ground where critters and insects might chew on it or use it as a highway up to my hammock, or where it might simply get wet and dirty.

Good tip. I don't let my tree straps hang to the ground either. It does give bugs easier access, can accidentally trap critters, & be a tripping hazard.

tensionless hitch. no knot. high stregth tie off.
just some of the many names for the hitch created by wrapping rope or webbing around an anchor. in abseiling/rope access it is used often, minimum of 4 wraps will hold the full weight of the rating of the rope on most surfaces. i use this to hang from polished 3inch metal pipes.
