Bidirectional hitch

Hi gang,
Looking for a productive discussion on a bidirectional hitch, something that could be used in a 2-in-1 lanyard.
Is there just the prusik or are there others out there? Show me your favorite!
 
I am not sure of a friction hitch that works both ways other than the prussic, although a second directional adjuster on the opposite end can work and I believe there is a bidirectional mechanical adjuster. Although I have no experience with it.
 
If look into a double-ended lanyard. One or both on the same d-ring.

Never been able to figure out a good reason at work. I climb with a climb line and lanyard, conifers or hardwoods.
 
I found three others that I have, and adapted the Distel, by adding more wraps on the bottom, to make it more like the Prusik.

The top left is the Autobloc, next to it is the extended Distel, the next two are Prusik variations. The first from T.L. Hamel, the other is the Gerard, kind of a reverse Prusik.

I previously used two of the English Prusiks on a swivel carabiner on a Two in one. The swivel was the key to help from tangling.

I'm really digging that bidirectional Distel. Looks very secure.

Why do you want a 2-in-1?



Have you seen the "motion lanyard" set-up? Used in big tree climbing, like redwood rec/ research climbing, I hear.

That's pretty much what is pictured above, except its made with a long rope, and the above is using one hitch cord.

Sean,
I want a 2-in-1 because it promotes safety (well, redundant tie in points, anyway) when working aloft. I'm new, and being able to jump limbs with the same cord (different snap, for ID) is simple for me.
Cheers
 
As far as augmented secondary SRS climbing systems for rec climbing goes, this Sterling thimble prusik, makes this an ideal lanyard accessory option, imho.

"...is great for rigging, climbing, and lanyard adjustment." ...according to Wesspur

Gorgio Fiori has a great version using a Paw Plate as the platform to fit a single hitch cord with two independent prusiks

This looks like a slick setup! I imagine under the right circumstances it would offer some really stable work positioning.
First lanyard I put together was a 2 in 1, was about 15 ‘ in total length with Prussics, shizels (?) to tend the prussics and 4 biners.
I found it to be cumbersome because I was only using one side most of the time. Having to fight the additional prussics to add length to one side was a pain.
Now it’s a single 15’ with a snap and a rope grab. Slack is daisy chained and readily available.
 
The 50' hook/grab/snap lanyard is essentially a secondary SRT system, to better augment positioning and movement within the canopy. A basic 15' lanyard's primary function is for a quick and safe tie-in, without the extended reach of a longer lanyard line. They both are highly valued components in my overall climbing system.
 
I’m saving my pennies now to set me up a system like that with that high priced hook. Have watched a bunch of guys on YouTube and here on treebuzz killing it with those things. Another tool for the box!

As you like it.

I like two different rope patterns. One for climbing line, one for lanyard. That keeps you tied in twice for cutting, and always tied in when hopping limbs.

Two lanyards of the same rope, essentially, can be somewhat confusing, especially while climbing through thick brush.

The double-ended lanyard may be more complicated.
 
I'm with you on different rope colors for different purposes.

When I used the DEDA the snaps were a different manufacturer from any other snap

To keep the ends in order I used a blue one and a red one
 
A single bidirectional hitch is great and all... But for the purpose of a 2 in 1 lanyard I don't see how it would be better than two hitches opposed to each other, such as Fiori's set up. Once used as a 2 in 1 the length of the two legs combined would always have to equal the length of the entire rope... If that makes sense. Whereas with two hitches opposed to each other you can have a belly in-between and each end is individually adjustable.

Ah, excellent point! If one has just snaps on each end and a single hitch adjustment in the middle, and a 50' rope, you would need 25' on each side when using it in a 2-in-1!
I hadn't noticed this yet, particularly because my existing 2-in-1 experience is on a 12ft cord.

OK, I'm convinced that 2 separate hitches would be necessary, in order to belly the rope between them for shorter connections. Bravo, thank you.
