Hitch cord for 9mm rope?

[withspark]

Howdy all,

I'm looking for recommendations for a hitch cord that would work well on 9mm rope. I am also interested in recommendations for climbing hitches that are releasable under load.

Thanks

That's awfully small for climbing line, going to be hard to grip. What brand is it?

Hi, thanks for the reply. It will be a variety of type B semistatic ropes, such as the Petzl Push rope. The use case is in a cave, but i figured tree guys would know more about hitch cords.

You always want your hitch cord to be smaller than your lifeline, but most hitch cords are 8 mm, so there won't be much of a difference. It sounds like you will be using a single rope, so some sort of device like a hitchclimber will be necessary to keep the hitch from locking up. As far as hitches go, my favorite is still the VT.

Could you elaborate on "the hitch locking up"?

Most friction hitches won't release well on a single rope... your body weight binds it up. On a traditional doubled rope technique it is only holding half of your weight, so it releases. Various devices are used in single rope technique to solve this problem...
