What is Static Rope - Knot & Rope Supply

[@alanmcrae8594]

Excellent presentation! You should have many more subscribers. Not sure why not.

[@jsummers1820]

This was very informative, concise and cost efficient. Thank you. Cheers.

Am I correct in thinking the “stretch” comes from what is essentially the braid or weave of the strands constricting or relaxing which causes the diameter of the rope to shrink or expand? I had thought prior to this that the ropes “stretched” somewhat similar to how elastic stretches, but if I’m understanding correctly, the actual material of elastic stretches which is different from the “stretch” on ropes such as these. Thanks for the vid and any help in explaining!

[@KnotAndRopeSupply]

There's a number of things that go into the "stretch" of a rope. Yes, construction of the rope is one of those factors, but the elasticity of the fiber itself has more to do with the stretch than all other factors. For example, polyester does not stretch as much as nylon or polypropylene and fibers like kevlar and Dyneema have even less stretch.

[@millea8]

@@KnotAndRopeSupplyInteresting! Thanks for the extra detail. Makes sense. Now I’m curious if there is documentation or a resource somewhere that details the estimated percentage of stretch the construction, braid style, twist, material used in the construction, etc. contributes to the overall stretch of the ropes. I wonder if this is just common knowledge across the different industries that use a lot of rope, but for the consumer like myself that’s just looking to get educated, it might be useful…short of just digging around KZbin and the web piecing the info together.

Another great feature of a dynamic rope is in a fall - that bit of stretch makes for a little gentler fall.

[@13Voodoobilly69]

I once fell while carrying a coil of dynamic rope but I still hurt my knees on the garage floor. 🤣😜

Nylon vs polyester static rope, what’s the pro’s and con’s thanks!

[@marvinostman522]

You stated that the static ropes can't be spliced by hand, does this include doing a flemish eye? With that being said is possible to a vflemish eye kin a static rope? Also is there a way to tell if a rope is core dependant or not other than knowing exactly what rope you are dealing with?

Nice job, John.

[@MrSingleJack]

Extremely nice presentation! It would be good to know the names of the speaker/writers/editors/etc. ... a job well done ... fine editing and scripting. Very much appreciated!

[@KnotAndRopeSupply]

Thank you! The speaker is John, the owner of Knot & Rope Supply. We typically shoot everything unscripted and produce/edit everything in-house.

[@alipiochristianandref.3336]

can this be used for hanging the hammock on tree?

[@KnotAndRopeSupply]

Sure, I would look at one of the smaller diameter static lines that we offer. But yes, a static rope can be used for this application.

[@akostadinov]

Can you point at a video showing static rope splicing?

[@KnotAndRopeSupply]

Due to the type of core that static rope has, it can not be spliced in the traditional sense. It has to be stitched.

[@ridermak4111]

Aleksandar Kostadinov Most arborists ropes are considered static (they are definitely not dynamic) and they are spliced all the time. Kernmantle construction can’t be spliced. Mountain climbing spokespeople don’t include arborists information and vice-versa. Just enter “arborists ropes” into KZbin’s search line and you’ll find tons of information. Arborists ropes have a variety of characteristics so be patient and watch lots of videos. Also search “arborists rope splicing”. You’ll also stumble into some crossover with sailboat rigging. Be careful buying from amazon and eBay. They sometimes don’t include important information. You want polyester, you DON’T want polypropylene. Thousands of pounds of difference in strength.

In mm???

[@KnotAndRopeSupply]

Just over 11mm.

[@ridermak4111]

Get yourself a conversion app !!! I like “units plus” !!! Don’t prove your helplessness and then smack the question mark 3 times !!! One inch is 25.4 mm Some real basic math will take you from there.

[@RooDavis]

@@ridermak4111 I was wondering the same thing, and a bit shocked to hear some weird fraction measurements 7/16 or 1/2 inch. I had no idea anyone talking technical roping still used these terms

[@ridermak4111]

@@RooDavis Months after the (unrelated) root cause of my nasty sarcasm....I’m sorry for that, Fredrik.... I agree that your surprise is logical. My fledgling interest in all things rope has revealed commonalities and differences between recreational climbers, rescue operations, arborists, tactical teams, high window washers, industrial access, sail rigging, lifting rigging, good grief, the sub-genres of equipment selection is head spinning. I think the main commonality is “SAFETY OF LIFE”. And about those antique fractions.....I blame the arborists. 🤫🤭 They sure are fun to watch though. They’ve got giant balls......and my respect.

[@RooDavis]

@@ridermak4111 you are right. I'm a climber looking for some technical information on ropes which I have always known to be in metric, KN, KG, Meters, MM, etc. I'm more use to hearing fractions and inches used when getting lumber to build the barn or the ranch fence. But later looking at 'knot and rope supplies' I realised they were not focused on climbers but more tradespeople, farmers, arborists, in the USA. My dad was born in 1937 and he would sometimes talk 7/16ths of an inch, but well before my time. Curious I just google to see only 3 countries in the world use the imperial system of meaurements, Myanmar, Liberia and USA, but even then I would think scientific and engineering people in US have upgraded to metric www.statista.com/chart/18300/countries-using-the-metric-or-the-imperial-system/#:~:text=Only%20three%20countries%20%E2%80%93%20the%20U.S.,body%20parts%20or%20everyday%20items.

[@cerberusbonsaiarboricultur774]

You're mixing up 'static' with 'kernmantle'....Static lines can be double braids, hollow braided 12 strand, or core-dependent kernmantles (like that lineup appears to be, am unfamiliar w/ un-braided cores) but static refers to dynamic capacity IE the rope's elasticity, not it's type, determines that. Atlas has way more stretch than any 3-strand rigging line, for instance. All arbor lines, climbing and rigging, are considered 'static' relative to other industries but there's a very strong case to be made for higher stretch (ie a nylon core, well for double braids, not much of a parallel-core type myself I like to be able to easily splice my own rope :D )

[@KnotAndRopeSupply]

Great point. In this video, we are simply pointing out the fact that static ropes (in this case parallel core with braided cover) are ropes with little or no stretch compared to other braided or three strand ropes. We should do a video about the variety of static ropes as well, that might be helpful.

Can i taste the Lovely Ropes? I LOOOOOVE ROPES! 😭😭😍😍

[@tittyrino]

Haha me to. I even love the sound gear makes like carabiners clicking etc. I’m a Recreational Tree climber and a gear junky!!!
