Things to Consider
As you’ve seen, there are a few different types of ascenders, and they are all perfect for slightly different tasks. It’s vital that you get the model most suited to your needs. That could be a hand ascender or a more compact model. Due to these differences, we thought it was best to create a buying guide to give you all the information that you need. We’ll go through all the key features and see how they apply to you while also answering any questions. We hope that by the end, you won’t be left with any doubts.
Things to consider before getting an ascender
There is plenty to consider before getting an ascender. The key aspect is knowing what type of system you want to be climbing with. After that, other key features, such as ease of use, dimensions, and weight limit, play their part. We also know that your budget is also going to play a key role in your decision. Here, we’ll go through those key features to help you develop a clear idea of what ascender suits your needs the most.
There are a few different types of ascenders. Foot models can be ideal for those who want to use their legs’ power but can be a bit ticker to use at the same time. Other ascenders, such as chest models, are great in a pulley system and can be very useful for emergencies.
Apart from that, you can find smaller models that you’ll push up in a system or handheld versions with large handles. Both are highly effective, and the best one for you will come down to personal preference in your preferred climbing method.
Left vs. right-handed
With handheld models, you will have the choice of either left-handed, right-handed, or both. Again this can come down to the type of climbing you’ll be doing. If you’re pairing it with a grigri, for example, you may prefer to feed it with your dominant hand, and therefore, you’ll want your ascender to be on the side of your non-dominant hand.
If you’re not using a grigri, you may prefer one on your more dominant hand. This will depend on your set-up, and some prefer to use two ascenders together on both hands. With smaller ascenders, this isn’t something you need to worry about.
Suitable rope diameter
Before buying an ascender, you need to know what type of rope diameter you’re going to be using. Not all ascenders are compatible with different ropes. There are, however, standard sizes, and these are usually in the 8-13mm range.
You don’t want to get to your climb only to find out that your rope doesn’t fit the ascender.
Weight limit and breaking strength
As with any type of climbing gear, you want to know that it’s going to be able to keep you safe. The weight limit plays an important role in that as you want to know how much it’s going to be able to hold.
The breaking strength is shown in kilonewtons (kN), such as the 4kN on the Climbing Technology RollnLock Pulley, but other times you’ll come across a more specific weight figure, such as the 225lbs on the KONG Ascender Climbing Lift. All of these ascenders will be ideal for almost everyone, but if you’re especially heavy, it’s good to double-check that.
What activities is it designed for?
There are many different types of climbing activities, and some ascenders are more suited for them than others. The Climbing Technology RollnLock Pulley, for example, is ideal for the likes of rope climbing maneuvers, rescue, and self-rescue situations.
If you want an ascender for cliff rescue, mountaineering, and crag activities, then the Wild Country RopeMan MK2 Forged Ascender would be perfect. It’s all about matching up the right ascender to the task.
Ease of use
You want all of your climbing equipment to be easy to use, and with ascenders, that means being able to open them effortlessly, releasing them quickly, and also gliding smoothly on the rope. If they don’t tick those boxes, it can be very frustrating.
The proper way to use an ascender will depend on the type of climbing that you are doing. There are several different ways they can be used. Some people like to use a pulley system, whereas others may prefer to push up with their legs. All these ascenders will come with instruction manuals, which will show you the correct way to use one. If you are unsure, then it’s best to consult with a more experienced climber who will be able to walk you through the steps required.
You can use ascenders for tree climbing freely, and for many people, this is their preferred method of using this gear. An SRT kit (single rope tree climbing) is often preferred, and this involves using a chest, foot, and hand ascender together. Other gear you’ll need includes a harness, carabiners, tethers, and, of course, your rope. This makes scaling a tree very simple and allows you to get down quickly too. This method can also be very good for those who love saddle hunting.
The wear and tear on the rope when using a high-quality ascender is going to be minimal. These tools are going to have an effect, but the rope you should be using will be more than good enough to take it. That being said, some are going to provide more wear than others. Due to this, some climbers don’t like to use ascenders where the teeth are too pronounced. This will be down to personal choice as others prefer to have a higher level of security a toothed ascender can give you.
All the ascenders that we’ve looked at here are brilliant, but the one that stood out the most was the Climbing Technology RollnLock Pulley. It is light and compact, and you’ll end up relying on it a lot while climbing.
While those three are great, the other seven options on our list are also very impressive. It’s important to know which type you need, and then you will be able to get the best ascender to match that. Once you do, you’ll soon find your climbing adventures to be easier than ever.
