Samson Tenex as a rigging line?

[basnighttrees]

Hey there, has anyone use Samson Tenex 5/8in as a rigging line? The sells person said he has been selling it to other tree services for rigging. I know it is great for slings. It looks really lose and would not hold up for natural crouch rigging. However if the rope stays under load maybe. Not sure if I want to invest 190.00 in a 200ft rope that may not be designed for rigging. Thanks for any input.

I remember reading somewhere that Tenex is not recommended as a rigging line, but my damn brain is failing me right now and I can't remember where I read that, and I can't remember why it should not be used...

Ah, yes, Wesspur...

"The 12-strand braid is very easy to splice, but makes the rope susceptible to plucking and abrasion if it is run over the bark of a tree as a rigging line."

If you need some serious working load, try a length of 3/4" Stable Braid.

I have used the stable braid before and if I remember correctly it had a lot of stretch. Plus using it for natural crouch was not a good idea because if the outside rope wears then all the strength is left to the inside rope, the one you can't see to inspect.

It's downright dangerous for rigging because it won't hold a knot under pressure without walking itself undone before your very eyes. Tenex has to have custom termination hardware or something.

Tenex won't hold a knot under pressure.

OP:

I forgot that you were looking to work with natural-crotch rigging... I like 3/4" Stable Braid and my CMI Block for false-crotch rigging, and for natural-crotch rigging, I use 3/4" Samson 3-strand Pro Master cause it's relatively cheap and has a soft lay, which I like. If your not down with 3-strand, maybe try using 3/4" arborplex 12-strand with a breaking strength of about 12k lbs.

Will the knot walk or creep on a bowlen or double fishermen knot?

I use SB all the time for natural rigging. Think about what this say, you would rather use a hollow core that is 100% capacity on the friction surface. What happens if you burn it on a rig and all the weight is on the compromised fibers? I want that inner capacity of the protected fibers when rigging big wood.

I've worked on big trees where we built in the cost of 200 ft of 9/16 because we were bidding at around $350/crew hour and it would pay to burn out the new rope work faster on the big wood.

I've done this a few times and sold the rope to my client at 50% retail with the caveat that it was degraded rope.

Thanks for the import. I will probably get the stable braid.
