Porty anchor

[Rocks_and_Trees]

I was just reading some old threads on FFC (thanks for reminding me jodytree) and read that some guys anchor their SRT with a port-a-wrap. Just wondering, Not the same porty you rig with, right?!

I can't imagine having one only for srt anchor, but i guess you'd have to if you wanted to use it in that application.

they make a small one that alot use for this, it comes in 3 sizes. But yes it is the same port-a-wrap

Yep, that's what we do. Bought a small one specifically for that purpose. Never gets used for rigging. We have the bigger one for that. It works well. Hopefully, something better will become available in the future.

i use the same one i use for rigging. when applicable. it works very nicely.

I was thinking of triing this, I just anit had the time to get to the store and get one.

Was thinking use 3 as anchors, use prusik from them to your climbing rope, figure 8 knot or alpine hitch in the end of climbing rope. gives you 3 different anchors case one breaks or get cut.

Trying one of those for what? I wouldn't want anything with a 50 lb load limit on any support system. Maybe a slack-tending pulley. That's it.

Saw the large ones rated for 150 lbs. And still made in China.

Iv'e never used it for tree climbing but...

for rock climbing I'd tie a mule knot for a BRD or a Munter.

Pretty standard.

 

[Knotahippie]

I remember the fig 9 knot from "on rope".

Pretty cool knot.

The fig 9 in the link there...I dunno' bout' that.

Asked a couple tree dudes they thought it was lame.

Seems to untie a little easier.

thats 3 x 150=450. LMAO wtf, everything is made in China.

it does lock off, plus it could be tied after it is put in the lock off.

I don't know, it's worth a try I belive

 

[DSMc]

Sorry man, I just can't see using this part as any portion of a life support system. Multiples or not.

You could generate 450 by sneezing on that setup.

Noone sees a problem with climbing on gear that you use for rigging? Wow. A porty sees more abuse than maybe any other piece of rigging equipment and you would actually anchor an ascent line to the same porty?

Would you climb on a rigging line too?
Would you tie into a rigging block?

Why is a porty the exception?

 

[Zac]

NO thanks! Sketch

I have a mini porty exclusively for life support. Back it up with a heat resistant prusik cord attached to the retension bar on the porty.
Being the co-inventor of the porty, I got the mini at no charge though. Have several proto types that I could use anyway.
I would not use a rigging device as a life support component at any time.

hey ed, i saw these last weekend at rei, they felt pretty crappy but i had the same idea you did, til i saw how low the tensil strength was

 

[poetmk]

any pictures of broken porta-wraps out there? i don't use mine for life support- use a grigi most of time - but the only time i've seen a "hurt" porty was when a log hit one of the tie-off ears and bent it a little. they seem pretty indestructible overall...

 

[treebing]

A lot of people tie off SRT on a gri gri. It seems pretty accepted.

to me,

dinky, complicated, plastic componented gri gri that if the directions are not followed carefully will result in failure?

or

big massive Steel Portawrap that takes minimal IQ to operate.

I also question the concept of treating rigging gear as somehow less important than climbing gear. To me this results in an unhealthy attitude of.

"its okay, that such and such is damaged, it is used only for rigging, we can use it to swing thousands of pounds around above your head with it as long as I'm not climbing on it."

If you couldnt absolutely positively with out a doubt trust your life on a portawrap, it should be nowhere near your jobsite. same for ropes.

Most of the time i use a trunk wrap though as that is even more bomber that the porty.

 

[tophopper]

Its not about rigging gear being less important than climbing gear. Its about the forces that rigging gear take vs the forces of climbing gear.
Climbing is far less forceful yes, and would I trust a porty for rigging if I didnt think it could handle far less climbing stresses? Absolutely not. Its a discipline, I dont climb on rigging gear, and I dont rig on climbing gear. Its that simple.
And yes, "It is ok that such and such is damaged" I will put property damage before injury or death any day. And to say "swinging thousands of pounds around above your head" gives testament to the type of rigging you do. Do you stand beneath your rigged load? And rarely is it thousands of pounds actual weight. The forces at certain times may be that or near, and if you are standing directly beneath all of that you are a fool.
I absolutely without a doubt trust my portys and rigging 100%, and when compromised, it isnt anywhere near my sites. But that doesnt mean Im foolish enough to use rigging equipment for life support. Name one climbing discipline where it would be acceptable to use anything other than "climbing equipment" for life support.

A grigri or I'd or any other belay device is not complicated at all. They are designed for user interface. IMO a porty is more likely to be improperly used and result in failure.
Yes its big heavy and made of steel and bomb proof.
If Im suspended on an SRT access line and someone on the ground is going to lower me, I would much rather be lowered on a proper belay device with built in safety and panic features vs. being lowered on a porty which has no such features other than keeping adequate friction by maintaining enough wraps. To say a porty is more fail safe is incorrect IMO. I completely disagree. I do think a porty can be useful for an SRT anchor, if only used for climbing and if backed up as Norm mentioned.

So Treebing, let me get all this straight now. You descend SRT on a hitch without a backup or heatsink, on a line anchored by a device that you use to "swing thousands of pounds over your head" with?
