Rigging krab idea.

[Joe Newton]

In my experience (I don't regularly splice any more) a large eye is a bit more forgiving with the final bury.

 

On a tight eye splice sometimes the cover can bunch up a bit of you haven't fully equalised the core/cover.

 

A bit of excess cover in a large eye is less of an issue.

Should have an MBS (from new) of around 45kn.

 

Any other markings on it, Mick?

Just this on the other side

W probably for Wichard btw.

So it would seem. Some nice shiny stuff on their site Wichard Marine.

I asked Nod a lot of years ago and that was the answer I got.

 

If the spice gets shock loaded there may be a small chance it disrupts the bury and throat of the splice.  At least with a bit more material in the eye, there will be a small amount of stretch before the bury takes the hit.

 

Don’t get me wrong, I used to prefer a tight splice to hold the krab in place but after a discussion with people far more knowledgable than I that is how it was explained.

 

 

 

I phoned Marlow ropes technical department and learned some interesting detail (my rope is a Marlow Draco, so seemed the best choice). He gave a straight no regarding the idea that it helps with shock loading, but had an explaination that works for me.

 

For a splice to give maximum strength, the splice throat angle should be small, that means the splice would be 3x or more, the size of the largest connector used in the eye - a very loose fit.

 

He said with climbing lines, its a compromise, people like a tight eye and it meets the EN standard, its good enough but it is not the strongest.

 

So, experienced riggers, what is the maximum size item that you would clip to a rigging rope?

70kN 12mm steel biners exist, so it still seems excessive.

The anchor side of a big ISC or DMM pulley. But yeah, mainly a biner.

 

I doubt anyone’s using these for trees but they exist.

I've got two steel fimbles on my cambium saver.

Sure. Rigging ropes though. You (probably) wouldn’t be able to poke them through rings. 
 

How does it feel having Marlow back up your hunch?

Well if their recent splicing cock-ups are anything to go by, it's the equivalent of phoning me for sex advice.
