Hey Richard, thanks for the nice video, I was just interested in the Kong Duck.. I couldn't help but notice you were referring to the ratings on the side of the Climbing Technology piece as a "rated load", and similarly to the slippage on the Duck. I feel obligated to point out that climbing gear ratings are completely different from industrial gear ratings, wherein--from what I understand--industrial gear is rated with "working loads" that are many or several times less than guaranteed breaking loads, so I've been told. Climbing gear's ratings usually indicate actual breaking loads. I would not be surprised if the climbing technology piece broke if loaded much beyond 20Kn. I'm sure you're fully aware, and 20Kn is a crazy load for personal use, but I just want to make sure there isn't any confusion. Cheers.
Is there any way to release the RollNLock so that rope can be payed out/slackened off without having to touch that tiny little switch? I'm asking about a feature equivalent to pulling on the release cord of the Kong Duck. I'd like to use the RollNLock as a replacement for a Prussik in a progress-capture system so that I can take the tension with one hand, release the progress capture with the other hand, lower the load slightly, and then have the progress capture re-lock when I take my hand off it.
I have the two priced very differently here in Italy with amazon with kong being almost half the price of the CT. I'm wondering if for lanyard length adjustment they should work the same, they should both hold 4kn right?
I wouldn’t do that. Use a friction hitch, or a different device that has been vetted. This device having only 4kN of arresting force means it would not be sufficient to reliably catch a fall on a belt. 4kN is easy to generate. Imagine a scenario where you’d need your belt to work-so say you’re on the trunk and the lineman’s tether is under tension at around 90° from the tree, and your feet come off the tree. This rough hypothetical would represent a fall factor of around 0.5. Relative to other climbing scenarios that’s not much, but that’s enough that kissing the tree would be the least of my concerns if I were using this device. I’d use these things for progress capture, not for fall arrest.
Oh that was just a little tether it is often used for retrieval ball when retrieving a climbing line. I think they're also used for securing shade covers and tarps and such things.
+wildairsoft1 From a user standpoint I say no. I often hear that ropes are the same but when you climb on them....different. Yale Blue Moon for example.
