CElanyard!

However, while you're at it, you'll also need the 8mm OP e2e sewn specifically for CElanyard. Nothing else works in the same way.

Why do you say that? I have created a poison ivy lanyard with the pinto with Samson ultra tech cord (tied in a distel) as the friction chord and have a ultra tech cord eye to eye spliced to a dmm ring in place of the thimbled cord of the CElanyrd. The pinto and adjuster are on a Petzl william ball lock and the ISC captive eye snap is on both ends. What am I missing? Pics soon.

Perhaps I should have been more clear in my statement. The sewn eyes are larger (longer) so that the sewing and resin/shrink tube tend to stay away from the rope. At the same time, the sewing itself is as short as possible. Allowing more useful (that is, pliable) rope available in the prusik. Splices, knots, and whipping or shrink tube are a bit bulky and can create too much friction between rope and sheave. And splices, as we know, leave a very inflexible area in the throat of the splice. Some folks may prefer that... I personally don't.

Hey, if you have it dialed in the way you like it, that's great! Most important thing is to have a system that functions well, reliably, and all components are compatible. Takes a lot of tweaking and patience.

Hmmm, a good place to start is the book "On Rope". Or maybe Treespyder's website?

The 5:1 is a "complex system". Meaning that parts move toward one another. It's a bit tough to get your head around unless you're real good at "counting T's" Think of it as a 6:1 rigged to disadvantage.

The 6:1 is simply a 3:1 acting on a 2:1

Hope that helps?

EDIT: Actually, it's not really a 3:1 acting on a 2:1, it's just a 6:1. But, you know what I mean...
 
Thanks Taylor it does- forgot what a great book it is
pg 243-244 'on rope' if anyone else is interested

Now do me one more favour and convince DMM to make a drop forged RW with kevins permission of course!!!
 
Hi everyone im new hear i want a ce lanyard just wondering wats a good length for normal climbing prunning and removals and what would the price be?? Thnx
 
ANSI Z133.1-2006
8.1.8 "Arborist climbing lines shall have a minimum diameter of 1/2 inch (12.7mm) and be constructed from a synthetic fiber, with a minimium breaking strength of 5,400 pounds (24.02 kilonewtons [kN] when new......."
There is more about the stretch and elongation. Then, there is the "EXCEPTION" about 7/16 inch (11 mm) diameter with "The strength and elongation ratings of the line selected shall meet or exceed that of 1/2-inch (12.7 mm) arborist climbing line."

8.1.9 "Prusik loops, split-tails, and work positioning lanyards used in a climbing system shall meet the minimum strength standards for arborist climbing lines."

In the video it's demonstrated in a 'choking' fashion, which would make it a single line technique.
It's your call. The human body will fail before the lanyard will. It's a very nice piece of equipment, with some features that no other manufactured lanyard has.
 
I understand now Norm, hadn't checked the product sheet. I thought you were referring to the prussik cordage, not the lanyard cordage itself. Silly they'd design it that way.

Here's a link to a lanyard survey. lanyard survey

May help with your decision.
 
Nice video, nice product. Thanks, Taylor. It would be nice to be able to buy a DEDA version: two identical setups, a long single rope around your back. You could move a lot of pulleys ... !
