Would this biner...

...meet ANSI Z133 standards:

If you don't think so, explain why not.

I guess its double auto locking. But for life support its not 23Kn. Its only 7Kn. I wouldn't use that for anything important.

Double auto locking = two movements in different directions to lock? and spring loaded?

 

[treedogg]

negative, not double auto locking, three distinct movements to open, like push button, twist, and open gate. and it is rated to minimum strength requirements. Not bad for a speed line or something.

 

[Jman]

Closed Gate: 30 kN (6744 lbf)
Open Gate: 9 kN (2023 lbf)
Minor Axis: 7 kN (1574 lbf)
Weight: 2.24 oz. (63 g)

I skipped over the closed gate and read the open and minor as closed and open. So it would meet the force rating.

 

[TMW]

Hint:

8.1.11 Carabiners used in climbing shall be self-closing and self-locking, with a minimum tensile strength of 5,000 pounds (22.24 kN). Carabiners shall be designed to release the load by requiring at least two consecutive, deliberate actions to prepare the gate for opening...

 

[Jman]

Ok I think I got it this time. Its not self locking. I would think the two consecutive movements could be debated. I keep going though the actions to open it and its quite akward. But its not self locking atleast.

Nope. It's "locking" mechanism is inadequate.

darn you beat my edit....

But of course!

Appears lame on the minor axis but the numbers say otherwise.

 

[Gord]

It certainly doesn't meet up to the ANSI standard (only one action necessary to prepare the gate to open, that is opening outward gate, and even that is arguable).

How are rope snaps allowed in the ansi regs?

 

[TMW]

8.1.10 Snap hooks (rope snaps) used in climbing shall be self-closing and self-locking, with a minimum tensile strength of 5,000 pounds (22.24 kN).

Whenver i read or hear about discussionn involving topics like this I take a step back and think....ansi is not some godly power who gave us these laws. The regs in ansi are written by people who may or may not have anyexperience with climbing or actually applying the gear in the situations they are makeing regulations for. Who decided 5,000? Why not 10,000? Why not 2,000? why not quad auto locking thumbprint reading biners? Who decided where the safety factor cutoff should be? I know that when this industry was brand new, the tensile benchmarks were based on market products current at that time just because they were what was available.

Anyway....i wouldn't use it simply because the gate is open wire design and can bend, get cought etc. But I'm sure it shall prove to have many effective uses. cool find Tom

 

[CHOPPER]

visually it makes me think too much and at heights i don't need that stress!

 

[Jamin_Mayer]

It may not be for everyday arbo's like us, but for the rock climbing world its brilliant!

They will sell lots of those.

Like treedog suggested; maybe it would be good for a speed line.

I wouldn't put my life in them. I would be afraid that a twig/twigs could somehow manipulate the gates to open.

Heck if cams could magically open on ascenders, then twigs could open those gates. Right?

(Just mess'n Mahk)

I'm gonna stick to Petzl Williams.

 

[Tom Dunlap]

When I saw the biner I wondered how I could add it to my collection. Life support? Nope...two gates of course but not 'two seperate and independent motions to prepare the gate for opening.' What else then? Speedlining...hmmm, maybe...

Still thinking about where they would fit in the tree.

It is a brilliant tool for the right application though. In trees there are too many things that move around in three dimensions to leave me confident in the safety of this biner.

I'm with Jamin and Treedog

 

[Treelimbjim]

Where would they fit in a tree? Between throwline 1 and throwline 2! Faster than a speedlink, more secure than a single wire-gate. Rather large for this application.

 

[Gord]

I think it may be useful to use in place of where most use a caritool on their belt. It would prevent small limbs from getting clipped into the biner while moving through the tree- something that happens all too often in our limby conifers.

THATS a great idea! PITA when my side biners clip a limb.

 

[No_Bivy]

That biner is plenty strong enough for life support, not good in trees where wire gates could get loaded wrong. 30kn is impressive for a wire gate..........i would take the whip on that biner. I use wire gates for quick clips on my harness, that might be a bit of a pain with that one.
