It can be used as a rappel backup, to ascend a rope, to escape a belay, for glacier travel and for rescues. The prusik uses 5 mm or 6 mm accessory cord that is joined at the two ends with a double, or triple, fisherman knot.
The most common length of cord is about 1. The prusik loop connects to the rope by wrapping around the rope and through itself to make a barrel. A clear and accurate example can be seen by watching the video below. This is not standard practice when making your own prusik loop or prusik hitch but would be possible by tying a loop, such as a double-figure 8 knot , on either end of your cord and attaching them together with a carabiner.
For a few examples of these, you can check out some of the products listed below. While many prusiks are fairly indistinguishable from each other, there are some minor differences that can improve your overall user experience. While users should never have to test out the strength of the product as this should be done by the manufacturers so that users can comfortably rely on it, we have listened to customer reviews regarding ease of use, durability, and overall experience.
After looking through the current marketplace, we came up with the following list. This pre-sewn prusik loop may look just like any other pre-sewn prusik loop, yet it is packed with subtle features that make using it easier. For example, the rope is supple and flexible, making it easy to bend and tie knots in — something that some other prusik cords can not do so easily. The braided exterior has been engineered to last a long time, and the overall construction is super resistant to moisture, which is helpful as a moist prusik cord does not grip nearly as well as a dry one.
The heat-shrinking tube applied over the stitching makes it considerably stronger than a knotted prusik loop.
It is affordable, durable, and everything you could need from a pre-sewn prusik loop and nothing more. Budget-friendly option, Pre-sewn ends ensure it is ready to use right away, Heat-shrinking tube placed over the stitched ends for extra safety, CE and UIAA certified. This budget-friendly pre-sewn cord is a little thinner than the 8mm cord from GM climbing featured above, which makes it great to use on thinner climbing ropes as it is less likely to slip under pressure.
It essentially has all the features that the 8mm cord has, except it is not quite as strong as its thicker counterpart, and while in most situations this is not a problem, that little bit of extra assurance might just fuel the confidence you need in precarious situations. While this is a little more expensive than the pre-sewn prusik loops above although still very reasonable in price , the eye loop design allows climbers to utilize this product in a plethora of different ways, besides just creating a prusik loop.
For example, you could attach strong carabiners to either eye loop to use this as a long quickdraw, particularly effective on overhangs. The cord is quite thick, and while unlikely to slip under pressure, there is a higher chance than when using the 6mm cord featured above. The GM climbing 8mm with eye loops is comparable to the Rope Logic Beeline and the Rope Logic Ocean cords, however, the larger eye loops make it easier to fit in larger carabiners.
We particularly like the kevlar fiber which provides a high level of heat resistance, as prusik hitches create a lot of friction which can, over time, cause damage to the cord. A worn part of the rope or basic human error may cause the knot to slip when it is not supposed to. While this is usually not the case with a Prusik hitch, it is something to be wary about during a life-or-death situation like rappelling from a high cliff or rescuing an injured person.
If you are planning to use your Prusik frequently for these scenarios, you may consider buying some pre-sewn Prusik loops. These are especially beneficial for Prusik minding pulleys. The knots themselves are sewn together to make them sturdier and far more durable. The stitching is covered by a plastic sleeve to protect the knots from abrasion, making the system last even longer.

The knot must be tied with a rope of diameter less than the main rope. So if you are using an 8mm or 9mm throw line you need to be thinking about a prusik loop made fromm 5 or 6mm cord. The closer the cord and main rope are in size the less efficient the system. You also need to balance this against using a cord that is so thin that a.
I made a couple of new loops today. Each one takes only a few minutes to put together. The first step was to cut the cord to length and then seal the ends using a lighter.
