ISC Reflex

The RRP has more of a flat plate that pushes against the rope doesn't it? Similar idea though, the more weight the more pressure.

The removable swivel is not easy to remove when the rope is installed so its not that much of a bonus, I doubt I'll use it that way. 

Looks not too bad just needs a bit of practise. In a video it looked nearly quick as a carabiner.

I wouldnt like the extra length of a ring, carabiner and the swivel.

 

Quite tempted, but no where has stock.

Sorbus has stock I think? 

 

I think you have to remove the rope from the bottom part, but not necessarily all of the links, and that will give enough space to remove the swivel. Not possible with rope fully in there. I'll take a pic tomorrow.

Added a magneato thingy, works as it should. I think ISC should make something specific for the Reflex, in red/black

Good to read you, Rupe!

 

Amazed you're still climbing.

 

I know a few people who have mounted the swivel direct to their bridge to run a more compact setup.

 

It would mean replacing the swivel every couple of LOLERs if that's your thing.

From 1m20 shows how its done. Open the plate, move the links out of the way, hold the spring and swivel pulls out.

Yeah,it's fiddly though.

Thanks, I think!

Another good point in the video, and true from my experience now, the two attachment holes for MRT differ in that one (the closest ) gives optimum slavk tending efficiency, while the second hole is not do good. 

 

So, those earlier saying the ZZ just swallows any slack that is intentionally put into their system, this does solve that issue.

Sounds good so far Rupe.

Get a vid up if you can.

Welcome back btw.

The real issue which I've only just been made aware of, is that the device is only rated to 12kn. I don't know how it can be life support with a 12kn rating, a friend was not allowed to use his at a recent climbing comp. He also told me in the manual it states that it's a class C device. I'm not sure what that means in real terms, it's designed to be used in conjunction with another climbing system? Two rope systems are not a mandatory requirement where I am in NZ. 

 

 

I'd have thought that those running the climbing comp would have a better understanding on equipment.

 

The 12kN rating is no suprise, a device like this will slip long before it breaks. It may be the only way to break test with a rope is to tie a stopper knot which would jam against the frame of the device - at which point the links are slipping and doing nothing. Or to pull it directly at the top link against the swivel eye without a rope but thats not in any way realistic.

 

These mechanical prussiks are not really covered adequately by the standards - and neither are actual prussik cords - they that go under EN795 Personal anchors and is intended for testing them as PPE slings. The tests have little related to its use as a friction cord.

 

Some details of the Zigzag here...

Unsure if ISC have similar details available for the Reflex yet.
