The Kong Duck vs. Climbing Technology RollNLock

[@UBO58]

Thanks a lot for showing the differences, Richard! I love the outtakes "It's pretty easy..."! :D

[@ahjtate]

Brilliant and such a well explained analysis of these similar devices.

[@RichardMumford1]

Thank you.

[@MrSingleJack]

Very comprehensive, Richard. Thanks. I particularly like the release tether applied to the RollNLock.

[@RichardMumford1]

Thanks JB. After doing that I couldn't help but think of your Kong foot ascender. ;-)

[@markuss.5322]

Thank you, that was very helpful.

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.

I heard it's pretty easy to lift it up over the pin.

[@sergeantcrow]

Good educational video... I am into rock climbing and not an arborist.... but that CT device would be my choice...

[@eyescreamcake]

Good video but I'm glad KZbin lets me play it at 1.5x speed...

[@tedjohn441]

Richard love your video;s and idea's I am building a Thunder sling. I think I will use your bungee cord trick that looks very slick grat idea

[@rjhennard]

so with the little cinch rope i can use it like a ropeman1 on a lanyard?

[@EliSpizzichino]

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?

[@RichardMumford1]

I am not a fan for a lanyard adjuster as they don't release under load. And that is not a needed feature of the Rope Bridge

[@nathanarievlis3985]

Okay, now...How easy would you say it is ,to get it up and over that pin?

[@trevethan82319841]

Hello I ended up getting the roll and lock manly because so I could have a multi purpose pully so it's less gear I have to carry

[@williaty]

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.

[@RichardMumford1]

7:30 or so in the video?

[@LuisSanchez-lu4cu]

Richard can the roll and lock be used for lanyard. I want to ascend and use it in a Linemans belt.

[@davidwarren719]

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.

[@RichardMumford1]

Yes, something about having a camera watching.

[@plemmons]

Can you supply a link to the lanyard? I must not be referring to them correctly when I search.

[@RichardMumford1]

Can you give me a timestamp or some reference to the lanyard you're speaking of?

[@plemmons]

@@RichardMumford1 the one that you are using to open the cam at about the 7:30 mark.

[@RichardMumford1]

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.

[@plemmons]

@@RichardMumford1 do you have a link where they can be purchased?

[@RichardMumford1]

Retrieval Ball with Cord www.wesspur.com/friction-savers/friction-saver.html

[@parharn]

Very nice comparison. I am just concerned about the cable ties that you used. I wouldn't trust them as they can break easily!

[@RichardMumford1]

I've used this for years now without problems. They just don't break, and even if they did it wouldn't be a problem. Thanks for the comments.

[@gravyblue]

My roll n lock won't grip a weighted rope.

[@RichardMumford1]

But it's really easy to open the cam, unless of course you're doing a video.

[@stephen1133]

I think we should still be boycotting Kong after they refused to recall those faulty rings that were used in climbing harnesses.

[@rakmawa]

Pretty easy!!! That is damn honest!

[@wildairsoft1]

Is poison ivy the same as lava and tachyon

[@RichardMumford1]

+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.

[@josevega1793]

Hello, you talk about slippage above 4kn/400kg, and I think is also important to consider damage to the rope. Regars.

[@RichardMumford1]

Agree, hard to know what that might be.

[@VisinskiRadoviBeograd]

Pretty easy indeed :)))

[@kidesqu]

Thanks. Its pretty easy jajajajaja

[@vladislavjisa]

picture 9.1 with Kong is possible just little bit different way www.iafstore.com/uk/kong/ascender-belay-device-duck-codp4318

да крутая вещь 2 в1

get to the fkn point!!!
