Cover for dyneema

They work, a bit better than most mechanical clutches, and are used by experienced people. It is very similar to the Chinese finger used in most dyneema splices, so there is good reason to 'trust' it.

But bare dyneema can be difficult and I am sure there are applications with loads over these fixture's ability. In that case, typically the Karver or Spinlock jammers are often used (If I remember correctly, you may need special jaws with the spinlock).

And there are applications simply not suited to any sort of clutch/jammer - need to belay them.

The textile clutches IMHO have three practical drawbacks - one is they need to be mounted where they will not be accidentally kicked or leaned on, two is their installed length, and three is the sleeve is a wear part (clutch jaws are theoretically wear parts also but a lot of people just ignore that).

Thanks for the information. Since double braid vs bare dyneema lines represent a significant price difference, it seems further research is worth the effort before it comes time to rig this boat.
