Ultralight C4 questions
|
1. Will standard C4's stop being made, or will they keep both for people that want stronger and more durable and lightweight options? I couldn't tell from the OR show reports |
|
theyll keep making the C4s |
|
1) Camalot C4s will continue to be made |
|
Pete, |

Khoi would you be able to post a picture of a made in usa c4 next to a made in china c4? I want to see the difference between the two |
|
I'm curious if the ultralights will have the same 2kn reduction in strength if clipped directly to the thumb loop instead of the sling. Also if strop hitching the thumb loop with a runner will be any different than with the cabled thumbs of the c4s |
|
From what I've seen, BD has said that the lifetime of the Ultralights will be the same as the regular C4s (minus the fact that they may wear more quickly with heavy use). The dyneema stem doesn't seem to be an issue, it's fully protected from UV radiation, which is what weakens dyneema normally and calls for retirement after 10 years. |
|
Actually its 10 years for say petzl soft goods regardless of use or exposure |
|
Oh great! That's all I need-more cams to buy... |

Also if strop hitching the thumb loop with a runner will be any different than with the cabled thumbs of the c4sthe 2kn strength reduction is due to less metal on the lobes so it shouldn't make a difference where you clip it. |

I am referring to the C4s losing 2kn strength if your biner is clipped directly to the thumb loop instead of the sling. I'm curious if the Ultralights are the same given the difference in thumb loop construction. Also wonder if the thumb loop can kink the same way C4s supposedly can if the loop is clipped directly and fallen on. |
|
My guess would it would depend on the plastic they used for it. Although the sling can't kink if the plastic is still hard (although it does look different maybe softer) there would still be the chance of it kinking and creating a sharp edge that could cut the sling over time. |
|
I like the dyneema concept. Could be good for salt water environs as well. Still, metal lasts longer than textile, so my first/cragging set I want durable. I think it is great that bd is keeping both as lines, especially with the price tag approaching 100$$. |

Oh, also meant to add I am very intrigued by the "Continuous dyneema loop". If they could make full on slings without bar tacking them together.... That would be amazing! |

That would be amazing!It's not a continuous loop. There is grey nylon stitching attaching the two pieces of Dyneema. It terminates at the thumb loop and you can see the stitching by looking through the clear plastic. |

Interesting, thanks for the heads up on that. |

That would be amazing!I've tried bringing that up too. It seems like weird terminology for a company like Petzl to use if there's no difference between this and a bar tacked sling. If they've accomplished true continuous loop dyneema, that's incredible, and I want to know more. But I haven't yet heard anything to this affect (or against it). |

Continuous loop is impossible.. there is no way to start a line of textile and make a loop without it ever breaking. There is always some kinda splicing that would have to be done. I would prefer a bar tack that I can see and inspect than some kinda hidden "continuous loop". |

It's just a matter of time. Ultrasonic welding will also start making its way into climbing textiles. |
