HRC for a friction saver

Can I use HRC or Beeline for a friction saver?
NOT as a prussic but as the main line that goes from ring to ring. Nice and compact.
Someone told me there are no dumb questions so I thougt I would ask.

Yes
 
That's a dumb question

I would say to check what kind of bury you'd use on the splice if you're just going to use knots then again check the strength configuration
 
well it all depends on the splice would be my thing. I know John talks about the high mod splice used for eye to eyes being designed for a hitch cord configuration where you'd be putting different types of forces on it.
 
I think the 8 mm stuff we use for friction hitches does not meet the strength requirements when used end for end like in a friction saver. I don't know about the 12 mm stuff. I think this is true of both HRC and beeline. It would probably be OK if knots were used instead of splices.
 
The strength of the splice when done like an eye to eye for a friction hitch is the weak link. This is not a standard splice and is only usable because of the line being doubled in a prusik or other friction hitch. Each leg of the hitch only bears 25% of the load. That is why it is usable in a hitch. Most of these lines are class 2 splice-able because of the type of material used, therefore, the bury is not long enough in a 30" eye to eye to be able to use them as a friction saver. I don't know about a longer line. Maybe the bury can be done so as to support an eye to eye being used end for end.

The strength of HRC is dependent on whos cataloge you look at. Wesspur says the line is 4200# and the core spliced prusik is 5400#

Sherrill says their HRC is rated at 6500#

x2. American arborist agrees with sherrill

This what the manufacturer says about it's product:

Are you thoroughly confused yet Jesse? I am.
Do you plan on knotting or splicing? And how long do plan to make it? And have you decided on which product you are going to use. Beeline or HRC?
 
Lol Norm.
I climbed on it once and then replaced it with some velocity.
The HRC I had in mind was used as a friction hitch for quite a while so I retired it. I was using double fishermans knots but was too spooked. I climb slow enough without having to worry about my FS breaking.
Thanks for the input guys.
 
I'd be happy to climb on a HRC friction saver.

If I was splicing it, I'd use much longer buried tails and I'd coat the hell out of the eye with maxijacket coating.

Why would you, when there are far simpler and cheaper methods? I used to make mine from 3-strand, but now I just use Tenex. It holds up just fine and is plenty strong. If one wears out I can make another in about 10 minutes for about 2 dollars-worth of rope. Use full-length buries and you have nothing to worry about.

Many of the indiviuals on this board dont have the option to say "Im not going to climb this tree because it might pick my FS". Tenex picks extremely easy. So of the trees that we have to climb (ie honey locust, kentucky coffee, black cherry and others) have extremely rough bark. We can not choose not to climb them because we are just doing it for fun. We have to complete our job. If the boss says "go crown clean that locust", thats our job. Tenex wont last very long doing that. For someone that can climb red oaks and sycomores everyday, it might last a while and be worth it.

would this make it un acceptable for SRT applications then?
