How to Tie the Double-Double Uni Knot [braid line to fluorocarbon leader]

In this video, you'll see exactly how to tie a double uni knot for connecting a braid line to a fluorocarbon leader. Also, you'll see a slight change to the knot that you should use to the standard "double-uni knot" which will give your knot a higher breaking strength... we call this knot the "double-double uni knot".
To learn how to tie our personal favorite fishing knots, check out:
www.saltstrong.com
At the end of the video, you'll see a head to head knot pull that will show which knot is strongest.
Although this is a great knot, it may not be the strongest option for your braid to mono or braid to fluoro leaders.
We'll continually scour the interwebs to find the strongest and most easy to tie knot out there, and you can see the results if you join our free email newsletter... all you have to do is go to www.saltstrong.com and and submit your email.
Finally, if you have any fishing knots that you want us to test or show how to tie, let us know by going to our site and submitting your ideas.

I’ve been using this ever since I watched the video to connect a 20lb flouro lead to my 30lb power pro braid and it has worked out great. Great clear explanation. 👍

[@labtrainer09]

I know this video is ancient, but so am I, and I'm just getting around to thoroughly researching braid-to-fluoro knots. My conclusion is that no matter how much testing is done, there will NEVER be a definitive answer as to which design is actually best for this difficult connection That said, the Double-Double Uni that is nicely demonstrated and explained here strikes me as as good as (and maybe better than) all the others. Determined to learn it, I watched the video again and again, eventually tying the knot while screening the procedure. I started with larger-diameter cotton twine (of two different colors) just to "get the hang of it." Then I moved on to using my chosen combo: 30-lb. braid and 30-lb. fluoro. By far the most difficult stage for me was TIGHTENING the knot(s), and I personally think that the order in which this is done wasn't emphasized quite enough here. Pulling on the tag ends vs. the whole "main line" in the correct order and to the correct degree is truly critical--at least in my experience. When the tightening goes well, the Double-Double Uni is very strong AND good looking. But when I make even a slight mistake during tightening, the knot is a disaster in every respect. But I'm getting better at the process, and I KNOW the effort is worthwhile. I hope others don't give up too early, as I almost did.

[@jamescraig8601]

Don't give up. I've tied every knot and stretch till they break. The double uni is by far the strongest knot I can tie in any type line. Like you said, the more you tie it ,the better you get. If you cross a line it will cut the knot right there. I've landed huge cats with it. Happy tight lines.

[@henryschmidt4009]

Thx for a very thural explanation and procedure of the double uni knot . I always used the blood knot for joining two line together with good success . It appears to me that the double uni knot is less complicated. Thx Henry

[@davidatkins6919]

Changing over to the double-double uni knot for my braid to flouro rigs! Great Video, Luke...

[@willfrednow]

Terrific! Ideal for surf casting. Many thanks! Superb vocals, clarity, and instruction. Greatly appreciate it.

[@Campers_Anonymous]

You made this incredibly easy, got it first try 🙌🏽 great instructional man, thanks!

[@crissurffishingde1499]

Great video...I will be changing up my lines to the double double Uni!

[@SunsTo7]

Hey Salt Strong, Great video. Thanks for the lessons on all of the knots. I fished as a kid for many years but never knew how to tie my own lures and hooks,now it is easy.

[@dmger14a]

Very well explained. Thank you!

[@mitchgarcia4591]

Thanks Luke! I've learned the fg knot from you. Will try this one also.

[@sparkyishii4583]

Great video. I have been using this double uni-knot. Thank you.

[@scottclark7740]

Good video. I used it today to put some braid and flouro together. Worked great.

[@grahamparish376]

Off to Panama 🇵🇦 again in Jan 2020. Double double uni knot is a must try. Huge fish out there. Thanks for the info.

[@jmartine]

Thanks for the great explanation of how to tighten it. I was always unclear about which strands to pull. It did it your way, and the knots came out beautiful!

[@Saltstrong]

We are glad to see that you enjoyed this uni knot video. Tight Lines!

[@senjieq]

Great video. I just transitioned over to using braid with a fluoro/mono leader and this knot made it happen. Everything held strong on my first outing. Thanks again!

[@Saltstrong]

Awesome news Jared! If you want to have an even better connect, I recommend giving the FG knot a try... it proved to be over 30% stronger than this knot while being much thinner too. Here's a link to see how it's tied: www.saltstrong.com/articles/fishing-knots/

[@johnbaumgaertner7746]

This is the video I saved on my laptop to refresh my memory when re-spooling with braid and another diameter of whatever. Very nice job of presenting

[@jthepickle7]

So smart to test both knots on the same line, under the same tension. I'm going to use that for other knots. Thanks

[@BlueLineFishing]

Great video, love the double double and will put it to use on our offshore trip next month. Thanks!

[@TheSexmachine43]

Great info, very informative and professionally done. Thank you for taking your time.

[@annbloss7706]

Great video. Got it the first time. Unfortunately lined up even and didn't have much of a leader line when finished. So back to adjust where I start. Thanks so much, I'm not really good with knots but this I think will be great. Thanks

[@dennissulik7050]

Thank you, I'll be trying that double, double uni knot when I go to Florida in a couple weeks. Well done video also.

[@Lightworks1111]

Good video. I use the standard d-uni. And am going to give the d-d-uni a try this year.

[@davidsugg6429]

I just tried this knot and it works very well saved a load of money on braid well worth doing not easy after suffering a stroke

[@allenbmooresharinginformation]

Good video with details on making a good line to line even better. The one additional detail to consider adding is the burning or searing of the tag end of your braided line. This keeps the braid from fraying.

[@johnmansell5097]

Thanks for the video, will now be using the double double in future. Looks simple enough.

[@richiev63]

Found over 5 years later. My new knot. Thank you.

[@hotmoffitt]

Thank you! I'm headed up to Harper's Ferry this afternoon to try out these beautiful knots you just helped me tie.

[@condolence1567]

[@primabellas6856]

You do a great job walking through each step. As someone who is very new to fishing, I really appreciate that.

[@Saltstrong]

Thanks for making time to leave the nice comment. We also put together a list of the best knots to use based on the type of lines and connection needs so that you can know which one to use... here's a link to that guide if you haven't yet seen it: www.saltstrong.com/articles/fishing-knots/

dude you make that look so easy. I learned the double uni-knot watching your video on it. I'm not sure I will need to double double uni-knot for bass fishing?? Your thoughts?? I live in land locked Okla. I can see the benefits of the double double for striper fishing at Lake Texhoma or Keystone lake.

[@musaeric4421]

Thank you for this simple knot

[@Saltstrong]

Musa Eric I'm glad to see that you enjoyed this double uni knot video. For braid to flurocarbon connections, I now recommend the FG knot... I did a knot strength contest and this FG knot was the strongest knot of them all while also being the thinnest. Here's a video on how to tie it: www.saltstrong.com/articles/fg-knot/.

[@brucer9409]

I fish fresh water bass exclusively, and learned the uni to uni from you. Still not comfortable tying it on my boat yet, but haven't experienced any failures yet. My understanding when I learned the basic uni to uni from you is that the knot worked best when joining lines of similar diameter, so I've used that guide religiously when choosing the pound test options of my FC or Copolymer to attach to a given braid diameter. At the end of this video I interpreted you to say that when your diameters were not similar, say your FC was more than a little thicker diameter than your joining braid, that's when the double-double uni would be more advisable. Am I understanding that correctly Luke?

[@mogtrader8]

thanks. im gonna try this. seems like this knot is very secured and won‘t have slippage of the flourocarbon.

[@DonSulis]

Excellent video, sir! Can't wait to try out the double-double tomorrow.

[@Saltstrong]

Hey Don, thanks for the nice comment. Although the double-double uni knot is great, I recently found one that I like even better while doing a strength contest on the top knots... here's a link to the results of the contest along with a detailed video on how to tie the winner (FG knot) the fastest way possible - www.saltstrong.com/articles/best-fishing-knot-for-braided-line.

[@ferrari4sale563]

Thank for the video.

[@mujahidali9818]

Yeah that is gonna work better for me they keep hitting my barrel swivel especially bluefish so this should help thank you

[@Saltstrong]

Glad we could help!

[@outaboutwithmarkjustine3183]

I just tied a standard dbl uni knot with 6lb braid and 6lb flouro, all I did was twist braid 13 times and flouro 6 then finish knots as required. The knot was so strong

[@XStormHail]

Bloody beautiful mate

[@IsaacFabela]

Helpful video!

[@tardbuster007]

well done!!

[@frankashby6235]

Thanks for the excellent video. I plant to run a fluorcarbon or mono "backing" directly to my spinning or baitcaster followed by braid. Generally speaking , is there a formula to follow indicating the difference in diameters to tie to each other or does one simply match the lb rating of the braid to mono or fluorocarbon?? Further to that line of thought how much mono/fluoro would you place on the reel?? 1:3, 1:2, or 1:1

[@leonwratt3969]

Thanks for the tutorial. I tried it with light braid and it kept breaking until I doubled the braid. Now super strong!

[@kats1978]

I always thought that I need to use complicated knot to obtain strength. But hey, just simple trick like this change a lot. And thank you so much for adding testing parts.

[@Saltstrong]

+katslmt Thanks for making time to leave a comment on this double uni knot video. If you're looking to maximize the strength of your braid to leader knot, then I highly recommend giving the FG knot a try... here's a knot strength test I did that showed the FG knot ~30% stronger than the double uni while also being almost half as thin: www.saltstrong.com/articles/best-fishing-knot-for-braided-line/.

[@pmhum]

Very good job. Very helpful

[@miahjay]

Watching this is very informational. But I couldn’t help but notice that fly that flew by you. I haven’t seen anyone so unbothered by a fly 🤣. Thank you for this video!

[@garykramer8852]

Just tied my first double double Uni with 65 lb braid to 80 lb mono leader. With my 67 yr old arthritic hands this was actually easier than the double uni knot. Thank You for a great instructional video. ( I used my saliva) lol...

[@Saltstrong]

We're so glad to you enjoyed this uni knot video. Tight lines!

[@williamgonzalez2702]

I love this knot. I will be using this knot. Just a tip that red back ground not good. Use white or blue is better

[@markrayton6385]

Fantastic video exactly what i was looking for. I will definitely try the double double knot. Thanks for sharing.

[@Saltstrong]

Thanks Mark! If you're using braid mainline and connecting to a stronger mono/fluoro leader, then I highly recommend the FG knot because it's proven to be over 20% stronger than this double uni while also being much thinner too... here's an article showing how to tie it: www.saltstrong.com/articles/how-to-tie-the-fg-knot/

[@markrayton6385]

Thanks very much for your reply. I will only be fishing a very light drop shot rig for small perch here in the UK so the double uni should be perfect. Thanks again.

[@mikepound9808]

Hey Luke - how about the double uni knot vs. the Albright knot - ever compared those 2? I can tie those 2 and the FG knot, but my current favorite is the double uni. I've tied and used the FG knot, but it takes awhile and has slipped on me. So the Albright and double uni are what I use out on the water. Just curious what you feel is the stronger of the 2.

[@capnstevoanythinggoes]

Thank you. I used another knot I found on KZbin for my first time using braid to fluorocarbon leader, and it simply unraveled after about twenty casts and cost me a 3.00 plus lure. I looked at and tied several other knots including the FG, Red Phillips, Albright, and Alberto knots. This one looks to be the best. It is also easy for me to tie because for many years I have used a single Uni Knot for different diameter mono to mono leaders, and mono to fluorocarbon leaders. I have had great knot strength and success catching fish up to and over 40 lbs on 14 lb test, and up to 60 lbs on 17 lb test, and no knot failures. I knew I was going to have to adjust to the quirks of braid, but trolling offshore demands less stretch for good hook sets and braid answers that need with braid to a long shock mono line for flex, then to flourocarbon leader of desired length for invisibility. Tight lines bruddah.

[@Saltstrong]

+Sonny Mac Thanks for making time to leave the nice comment. We found an even stronger connection for braid to mono/fluoro shortly after making this video called the FG knot... here's a link that shows the easiest way to tie it: www.saltstrong.com/articles/fg-knot/.

[@jessemellingeriii5244]

This is a good knot, but maybe not the most applicable knot for all situations. I trout fish most of the time with 6lb braid and everyone knows how good of eye sight they have which makes fluoro leaders necessary. I just pull off 4 or 5 feet of fluoro and cut, then connect to my braid with a surgeons knot. I lay about 4 inches of the tag ends of both braid and fluoro side by side, grasp both ends and make a loop. While holding the loop with one hand, I take the fluoro leader and the braids tag end and pass them both through the loop 4 times. Then you grasp both sides of the knot where the tag ends are and start to pull tight. But before you really tighten the knot, make sure to wet the the knot first with spit for lubrication to reduce friction which could weaken the knot, then pull the knot tight and trim the ends. I like using this knot instead of the double uni because I can tie it in half the time. I am not gonna say this is the strongest knot you can use for all situations, but I will say with a properly set drag, you should have no problems with it. I fish with nothing more than cranks and jerk baits for trout and I never had this knot break. I've had break offs with my connection to the lure, but never my braid to fluoro connection.

[@charissyros_greece1712]

[@bullbars1822]

Ok, first time for braid this year after 40 years of fishing small ponds and rivers. Boy do I need a magnifying glass. Braid is so thin that I had to turn on extra lights to see it. Thanks for the knot tip, I'll use it faithfully and teach my kids how to tie it also.

[@fisherman5678]

ApexPredator yes you should be good

[@TRustyOne]

Good review, thank you. Have a question though, what length would you have your leader by having this type of knot?

[@Saltstrong]

That depends on what you're targeting and how much casting you'll be doing. Here's a detailed post about making leaders if you are going to be doing a good amount of casting: www.saltstrong.com/articles/how-to-tie-a-fishing-leader-for-snook-redfish-seatrout/

Will this work on a 30 lb braid with a 10 lb leader? This looks like a good knot and easier than the FG knot.

[@nolascoconcepcion2785]

Thank you

[@fearnofish5am1]

Good video. Helps a lot. Going to try it out today

[@bobbarnhill8557]

Great knot for certain applications. The GT knot or improved Albright/Alberto knot go through the guides better and have tested stronger.

[@joegarcia3154]

I never allow my leader to pass through my rings because it wears them down or ruins them in the long run. I go 2 feet max but still keep the leader outside the last ring of my rod tip. Unfortunately though my casting is not as accurate when using soft plastics "if" I'm casting far. Plus a long leader will throw off your cast when passing it through the eyes of the fishing rod. The plus side of a long leader on braid though is that fish won't easily see my fishing line and spook off. I do however use about a one foot leader when fishing top water for better maneuverability. Your thoughts? 🙂
