For a long time I wanted to write an article on the best prusik cord products. The reason - I know some folks are somewhat confused about this important piece of accessory and its usage.
A prusik cord depends on one of the most favored climbing knots in the rappelling field - the prusik knot. In my earlier posts, I wrote about climbing knots and ways to tie them. So, check those posts in case you want to find out more on the topic.
Let's come back to prusik cords. They're essentially used for creating anchors. Plus, many individuals use them for applications in tree work and climbing. It's advisable to have a few of these useful climbing utility cords in your backpack.
This is more so because they occupy very little space in your gear bag and carry lightweight. You can make these useful accessories yourself if you know how to do the job. If you don't possess the know-how, order them pre-sewn and get ready for the action.
Speaking honestly, you might get wrong with each of the two options. Still, I'd recommend using pre-sewn cords if you're a beginner or just getting started in the field.
As well as saving hassles on tying them together, you'll free up time to prepare yourself for outdoor adventures. Furthermore, the use of a pre-sewn cord ensures that the cord used for creating them comes with the right thickness and length.
Also, there's hardly any risk of the knot getting undone because they're pre-sewn meticulously. That's a big plus, in my opinion.
If you want to bag the best cord for making Prusik utility loops on your own, you'll find useful details at the end of the article. As of now, I'll suggest a few pre-sewn prusik cords that have demonstrated their reliability already.
As a result, the cord gains some firmness; so, be prepared for that. However, it assures that durability won't be an issue for quite a while.
Moreover, the loop ends come machined-sewn and shielded with a plastic sheath (heat-shrink). I did use one of these sturdy cords in many situations. In my opinion, they do an excellent job for the price they come.
With 8mm thickness and 30-inch length, GM prusik cord carries a rating strength of 4.500 lbf. You can also use it for rescue situations, backup for belaying, tandem rappelling, and ascending assistance. Arborists also use them a lot.
You may use this durable prusik cord for various applications, including tree work, rappelling, anchor creation, or climbing. Boaton's prusik cord was made using a 10 mm durable polyamide cord. You can find it in two variants - 40-inch and 24-inch.
In addition to its quality pre-sewn nature, the product was designed to cause minimal damage to the main rope. Additionally, the cord can work in both directions. It all depends on how you wish to use it.
It's a reliable and flexible product that averts the hassles of making your own substandard cord. With top-notch stitching, the metal grommet ends stand unmatched. Also, the product comes at an affordable price. However, that's usual with other pre-sewn cords too.
Their price varies based on what you choose. What distinguishes this pre-sewn piece from others is the fact that it carries a tensile strength of 3.200 lbf, which renders enough durability for any use.
Furthermore, it's a dynamic Prusik Cord that elongates to a particular degree, depending on the force you apply on it. For example, it'll stretch by 19.4 percent at 300 lbf.
On the other hand, a 600-lbf force will cause it to elongate by 29.3 percent. Here, I'd like to specify that this prusik cord is sewn using 277 polyester threads. The sewing itself looks well done.
4) Kissloves Outdoor Cord (Pre-Sewn)
Kissloves carries a good reputation in the rappelling and climbing segment. Their pre-sewn alternatives to prusik cord are available in three colors - Blue, Red, and Orange. Each cord features a dependable polyamide build and heat-shrink plastic covers on the sewing spot.
By this time, you might have noticed that all the cords mimic each other in design. Yet, they differ in terms of elongation levels and strength.
When it comes to strength, this product can stand up to 4.850 lbf or 22KN. It offers better resistance to abrasion and moisture. Also, it can replace other knots, such as Bachmann knots or French knots.
The length of the cord is 40 inches or 24 inches. However, the diameter of each variant is 10.5 mm. So, you have the option to choose whatever variant fits you, depending on your requirements.
The product carries a strength rating of 4.850 lbf or 22KN. From my inferences, I can say that the cord is double-braided. So, you can enjoy some degree of moisture and abrasion resistance. With a diameter of 10.5 mm, the piece looks similar to the one I presented above.
Since pre-sewn prusik cords share a traditional design, they all look similar. All you should do is choose the one that reposes confidence in you. In the end, each of these five products on the list will work as desired.
Prusik Cord FAQs
1) Should you detach the plastic wrap surrounding the stitching?
Some folks have asked about the plastic wrap that covers the stitching on these types of products. If you're planning to detach it, think again. Let me inform you that it's a bad idea.
Why? Stitching on prusik cords delivers better quality, and there's no doubt about it. Machines do it automatically. However, this doesn't indicate that the cord material is unbreakable.
The plastic heat-wrap offers resistance to abrasion. Not just that, it ensures that the stitching won't get undone even if you apply a higher amount of force to the cord.
Don't try to remove the plastic even if you believe that detaching it will ease your legwork. Perhaps, you could easily set up the cord without the cover. However, you may jeopardize safety, and that I don't recommend.
2) Does the Sterling Hollowblock 2 Loop offer a better alternative?
The Sterling Hollowblock is an appealing option to a traditional pre-sewn prusik cord. It has now upgraded to its second generation.
Although it offers a comfy grip like the original product, this improved Hollowblock version provides much better abrasion resistance. Even better, it's comparatively more durable than its earlier version.
Made out of aramid fiber, the Hollowblock is actually a 6.8 mm hollow braid. The aramid fiber is sewn into the loop. You can find the product in 19-inch and 13.5-inch variants. It claims to have a 14KN breaking strength rating.
The 13.5-inch variant may work best for your situation, depending on your specific requirements. For Klemheists or French prusiks, the 19-inch variant will give better results.
Just be sure to see whether the hook or prusik is dressed properly or not when in use. The reason - the Hollowblock might slip a little otherwise. Generally, the product is meant to work on ropes with a minimum thickness of 7 mm.
3) Is Hollowblock better compared to the traditional pre-sewn prusiks?
In my opinion, it'll depend on the set up you use. I've personally worked with each of the types. I must say that I was delighted with both products. Still, I discovered that the Hollowblock might be more flexible in general.
4) What's the best nylon accessory cord to create knots?
At times, you may not feel like relying on a pre-sewn cord. Perhaps, you wish to tie the knots yourself. If this is the situation, you must use a sturdy nylon accessory cord. However, you ought to know the right size for the job.
If the cord you choose is extremely thinner on a thick rope, the hitch might obviously get too grabby. As a result, you can't manage it effectively after putting some load on the cord. On the flip side, a thicker cord won't grab properly. So, you'll need to use additional wraps.
I'd recommend you to begin with a 4 mm diameter cord. Still, I won't endorse it for prusik knots. Going 30 mm lower than the main rope's diameter is one thumb rule that you should follow. By doing so, you can be sure that the prusik will hold on as desired.
People mostly use 6 mm for personal prusiks. Yet, 7 mm or 5 mm can deliver desirable results too. The lack of strength is the reason why I won't recommend 4 mm. You need a cord that should stand up to abrasion. In my opinion, 4 mm is way too thinner for that job.
When it boils down to tensile strength, look for anything between 7 and 10 KN for cords between 6 mm and 7 mm. A wide range of cords exists right now. Here, I'd recommend picking your accessory cord from a brick and mortar outlet. You know why?
You get a chance to physically check the product and find out whether the cord folds or not. This will indicate how well it should work for any prusik. Take a cord and have its two sides folded between your fingers.
The cord should work well for a prusik if it folds totally flat. If you notice a larger eye at the fold, your cord won't grab properly. You'll have to keep looking. Still, if you wish to buy a cord that works fine for most applications, consider GM Climbing's double-braid cord (pre-cut accessory).
You can find quality prusik cords in three ways. Firstly, you may tie them yourself. The second option involves picking a pre-sewn prusik. Lastly, you may buy the Sterling Hollowblock as a better alternative to other options.
Your selection could vary depending on your liking for knots, your experience level, and your principles. I can't suggest one solution over others. Yet, I can say for sure that pre-sewn prusiks are much practical and reliable these days. Of course, the choice is yours. I just hope that I helped you find your match.
