Top 7 Best Rope and Rappelling Descenders

Best Rope and Rappelling Descender

There are different types of rope and rappelling descenders in climbing. They range from figure-8s and bobbins to racks. Usability and choice of the descender work hand in hand.

Thus, descenders may be designed for quick rappelling, lofty heights, firefighting, and law enforcement jobs. The post below is a guide aimed at helping you understand descenders. 

What are Rappelling Descenders?

A rappelling descender is a rappeling mechanism that assists you when climbing down a mountain or a cliff using a rope and the rappelling descenders are usually used in any type of rappelling where ropes are engaged.

And here is a bit more sophisticated explanation of how descenders convert energy to move the rappeller’s body down the rope.

The rappelling descender converts rappel of friction generated from rappelling into heat energy. For one to rappel, the power on the descent needs to be channeled somewhere else to stabilize the descent.

When friction-generated heat is dissipated on a fixed rope, rappelers can position themselves on any rope part, aka going down the rope.

How Do You Use a Rappelling Descender?

How you use a rappelling descender is hinged on the type of descender you are using and the outcome you are looking forward to. Most climbers are comfortable with the figure 8 descender for rappelling.

To use a descender, you have to fix your rope in it properly. Start by disengaging the device from the carabiner and sending the rope’s bight through the figure 8 bigger hole. Again, send the bight through the small hole and leave it inside the shank of the descender as the bight is tightly pulled. 

Now clip the carabiner at the base of the small loop of the descender. The setup allows you to use your hand for braking and controlling the tension.

As a result, you can control the speed of your descent. Your barking hand should grip the braking rope while the other one grips the part of the rope below it. 

What You Should Know Before Buying Rope Descender?

Rope descenders are the next generation of descenders that are designed to provide a safe descent. They have been designed to do this in situations where there is a need for controlled descent, and they can be used as an alternative to rope ascenders.

There are many factors that should be taken into account before buying a rope descender. These include the type of rope, type of terrain, and the level of difficulty in climbing/descending.

In this article, we’ll explain how a rope descender may make your climbing experience a little bit easier and when and if you might need one.

What are ascenders and descenders?

A descender is a device that slides down a rope or cable to control the descent of a person or object, usually in an emergency. The name comes from the action of sliding down. An ascender is a device that assists in ascending a rope or cable, usually in climbing.

What is a Descender in Rappelling and Climbing?

A descender is a device that allows a climber to safely control the rate of descent. Descenders are used in climbing, rappelling, and caving.

Climbers use them to descend from the top of a climb or rappel down from an anchor point. Rappellers use them to descend from the top of a cliff or other more vertical structure. Caving enthusiasts also use them for descending into caves and mines.

Rope-descenders are another means of safely descending a rope, either after a route is completed or when mountaineering in general.

Precautions while using a rope descender

This first point cannot be emphasized enough, so we have bolded and underlined it.

Never rappel without tying a knot at the end of the rope.

Be sure to tie a knot in both ends if you’re rappelling down both sides simultaneously. Climbers, both novices and professionals, forget this little detail every year and end up paying the cost of their lives.

Even though covering every single situation is impossible (remember that rappelling is considered a dangerous activity), it is worthwhile to figure out how you will protect yourself. Before you begin your rappel, consider the following tips.

  • If you are rappelling using a descender, it is a good idea to use a prusik loop to keep the rope close to you and stop you if you loosen some rock from above and fall unconscious.
  • Ensure that all the weight-bearing equipment does not break during operation due to wear and tear.
  • Before you bet your life on your knots, double- and triple-check them.
  • The rope should either touch the ground or extend beyond the next anchor point from which you intend to rappel.
  • Make sure no rocks or trees block your descent.
  • Before descending, make sure that all of the equipment and processes are familiar to you. If possible, try setting the system up at a very low height at home to get some practice before your life is at stake.

What are the Types of Descenders Used for Rappelling?

There are three different types of descenders – figure-eight device series, bobbings, and racks

Questions and Answers About Rope Rappelling Descenders

Is a Figure 8 Descender a Better Option?

Figure 8 descender is a versatile piece of equipment that has a multitude of uses beyond just descending.

The lack of moving parts does mean it is considerably more durable than some of the newer designs on our list, but it does take a little longer to understand how it works before you can use it safely.

Comparing its design to other designs is purely a matter of personal opinion and will largely depend on how you intend to utilize it.

What is a Rappel Ring?

A rappel ring is a piece of equipment used in rock climbing, often at anchor points. Rappel rings are typically made of metal, aluminum, or stainless steel. They are used to attach ropes to the rock face and can be used as a safety measure if the climber falls.

What is Figure 8 Rappelling Descender?

The figure 8 rappelling descender is metallic equipment shaped in an 8 form with one loophole larger than the other one.

This gear takes advantage of a big surface area connected with ropes to produce enough friction and greater efficiency when rappelling. The figure-8s work uniformly with harnesses and locking carabiners to guide the descending climber on rappels. 

Can You Use a Belay Brake as Descender for Rappelling?

Yes, climbers may use belay brakes when rappelling. Rappelling with belay brakes is safe. However, you must understand how to use them correctly. There are several various belay brakes models, with their advantages.

Internal parts are used to halt rope from going thru the shaft in a belay brake. This would be usually accomplished by including a camalot into the mechanism that enables the ropes to travel in a single direction but prevents it from going opposite. One of the most standard belay brakes is the Petzl Gri-Gri

However, when using the belay brake when rappelling, you will have to use it in the same manner used when belaying. But there is no spotter on the other end.

The braking hand is not to be loose on the rope, just as in belaying. Then conduct all the safety checks, such as checking if the carabiner will attach the belaying brake to your harness. 

Also, check if there is a stopper knot on the end of your rope. The techniques you perform using a belaying brake will differ depending on the make of the brake. It would be wise if you take your time to familiarize yourself with the brake before attempting to do a full rappel

What Descender Device is Used for High-Speed Rappelling?

The 3M™ DBI-SALA® Rollgliss™ is a renowned top-speed rope descender. It’s applicable in emergency rescue rappelling. The descender features a snap hook, braking trolley, and friction bars made from steel. It’s perfect for high-speed rappelling involved in extractions.

It has extra ears that aid in shutting off the descender. The figure 8 rescue descender’s key benefits are its lightweight nature, affordability, massive weight resistance, and simplicity of operations. 

What Does “50kn” Mean for Rappelling Descenders?

50kn on rappelling, also called 50 kilonewtons, is the amount of force that a rope descender can handle without breaking. For instance, 50kN, which is equivalent to 5000kg, means the descender can resist 5000kg force. If the weight is somewhat exceeded, then it will break off. 

What is Rappelling Rescue Descender?

Rappelling rescue descenders are descenders purported for specific use in rescue operations. They are descenders common with firefighter rappelers, and unlike other descenders, they are made to resist huge amounts of weight as an add-on to the high efficiency. 

Which is the Best Canyoneering Rappelling Descender?

While canyoning, the best rope descenders are the CRITR2 and the ATS. Additionally, the Hoodoo-SL has proven pretty functional in modern rappels. They all work similarly, are adaptable to any environment, and are pretty safe if applied to the proper purposes.

They adapt to various resistance levels, which is the most important characteristic of good canyoning equipment. Also, they are designed for a different angle on overhangs.

What is an Automatic Rappelling Rope Descender?

Automatic rappelling rope descenders are descenders that have a self-braking mechanism. They are vastly deployed in search and rescue and normal descents. 

What is a Rappelling Descender Plate? 

Rappelling descender plates are similar to descenders, only that they are made to be lightweight and can be used in different scenarios. They are normally below 8 ounces with descending configuration for double or single ropes.

Also, a rappeler may choose not to use extra friction by using a locking carabiner. Descender plates are common equipment associated with first responders, SWAT, and the search and rescue teams. 

What is a Stop Descender in Rappelling?

A stop descender in rappelling is a self-braking descender. They are designed to stop a descent when the braking hand is released. It has an asymmetric bottom which constricts the rope. This configuration protects the user should he fall unconscious during the descent.

Is an ATC Belay Device a Descender Safety Outdoor Rappelling Device?

You can rappel with almost every device used in belaying, including the ATC. The techniques involved are similar to the belaying techniques. The ATC device provides friction to allow the handling of bodyweights when rappelling. It’s the same design that will also catch in the event of a fall.
