12 best ascenders
Ascenders are essential tools used in the realm of climbing and outdoor recreation, particularly in activities like rock climbing, mountaineering, caving, and tree climbing. They are mechanical devices designed to facilitate the upward movement of a climber along a rope while preventing them from descending.Ascenders are a fundamental component of belay rigging and play a crucial role in ensuring safety and efficient progress during vertical ascents.
Key characteristics and functions of ascenders include:
Grip Mechanism: Ascenders typically have a grip mechanism that clamps onto a rope when weight is applied from below. This grip allows the user to ascend the rope by pushing or pulling on the ascender.
Teeth or Cams: Many ascenders feature teeth or cams that provide a one-way locking mechanism. When loaded, the teeth or cams bite into the rope, preventing the ascender from sliding downward. This design ensures that the user can ascend the rope with ease but can easily stop and hold their position if necessary.
Handle: Ascenders are equipped with a handle that users can hold onto and operate to move the device up or down the rope. The handle is usually ergonomically designed for comfort and control.
Attachment Points: Ascenders often have multiple attachment points, including a primary attachment point for connecting to the harness and secondary attachment points for additional gear or safety backup.
Materials: Ascenders are typically constructed from lightweight and durable materials, such as aluminum or stainless steel, to withstand the rigors of outdoor use.
Compatibility: Ascenders are designed to work with specific rope diameters. It's crucial to ensure that the chosen ascender is compatible with the rope being used.
Versatility: Some ascenders are designed for use with single ropes, while others are intended for use with double ropes or twin ropes. This versatility allows climbers to choose the right tool for their specific needs.
In climbing scenarios, ascenders are often used for various purposes, such as:
Ascending Fixed Lines: Climbers use ascenders to ascend fixed ropes or lines that are anchored in place on the route.
Aid Climbing: In aid climbing, ascenders assist climbers in ascending sections of the route where traditional climbing techniques are impractical or too difficult.
Rescue Operations: Ascenders can also be employed in rescue operations to ascend or descend ropes to reach injured or stranded individuals.
Proper training and familiarity with ascender usage are essential for climbers and outdoor enthusiasts to ensure safety and efficiency during vertical ascents. Additionally, regular maintenance and inspection of ascenders are crucial to ensure they function correctly and reliably in high-stress situations.

User questions & answers
Question: | Can you use the Ropman to rappel |
Answer: | No. Please don't try and use this device to rappel. It is an ascender. It shouldn't be used for descending as you're highly likely to hurt yourself extremely badly if you do. |
Question: | Will it work with 3/8" double braid rope |
Answer: | I am using a multi strand jacketed rope in 3/8 size. I don’t know about braided rope. |
Question: | Will it work with 3/8" double braided nylon rope |
Answer: | If you mean "work" I'll assume you're thinking that the 3/8" will fit in the ascender. The short answer is yes, as the WC Ropeman is engineered for 7mm to 10mm ropes. The 3/8" converts to 9.5mm. The quality of your rope choice has direct bearing on your safety and without knowing more about it, I can't recommend your rope and that ascender together as a safety line, restraint or back-up. Good luck. |
Question: | Difference in size between OS and 10-13 mm |
Answer: | OS is One Size, and is the same as the 10-13. |

User questions & answers
Question: | How much weight can this support |
Answer: | The Petzl ascension is certified to the EN 567 standard that says 4kN (900lbs) static load without destroying the device or rope. The key is static load. The device can withstand higher static loads to about 6kN (1350lbs), but any dynamic load applied from 4kN (900lbs) to 6kN even for a millionth of a second will eat your rope to shreds. The general rule is toothed cam devices eat rope at 4kN (900lbs), so don't use it as a rope grab, fall arrester, or progress capture unless you really know what your doing. The EN12841 type B standard tests show that it will handle dynamic loads over 4kN (900lbs), but it becomes very depended on what type / age of rope is used. Its a hand ascender for body weight (static loads), if your using it for something else consider another device. |
Question: | What diameter rope is this for? ca i use it with 12-strand arborist climbing rope, 1/2" by 150' blue ox rope |
Answer: | It will accept 8mm to 13mm rope - Arborist rope will be fine. |

User questions & answers
Question: | Will this work for a lineman’s rope |
Answer: | I use this as a chest Ascender. (11mm ladder safety rope) This ascender is best on a vertical line. I use a rope grab with a heavier U shaped aluminum body & cam for tree/pole flip line. |
Question: | Will a 12mm rope work with this |
Answer: | Yes! It is marked "8-13mm". I have used it with 11mm, 12mm &13mm ropes. That is 7/16" to 1/2" diameters. |
Question: | Can I lower myself with this device |
Answer: | No!!! It is an Ascender- as in: GOING UP!!! It will slide freely up a rope; But, It Locks if the eye hole is pulled downward. It is a safety device to catch you if you slip or fall. It can be used as a back-up device for a Descender. The silver tab on top when pulled toward the eye hole allows it slide down your rope with NO braking control. It works well as a Fall Arrest Device! It is a very compact & very light wieght! What you want is a Decender. Figure 8's; Figure 8's with ears are the least expensive. Search Amazon for "NewDoar Climbing Stop Descender" It is a hand controled Decender. Read the Amazon Page carefully. There is a lot of good information in the Listing; Questions & Reviews!!! Whatever hardware you buy; look for CE Certification- your life depends on it!!! I bought a 11mm(7/16inch) LOAD RATED CLIMBING ROPE to use with this descender (12mm & 1/2inch were too tight- same as in review). Be Careful & Keep Asking Questions! Knowledge is key to climbing safety! Ed. |
Question: | Will this stop me from falling |
Answer: | Hi! This is an ascender or could be used as a progress catching device, which means it is designed for a static load or a small slip (in its second function, as long as there is still some rope above you to lower the shock load). It is solidly built and easily slides up. |

User questions & answers
Question: | What is needed to attach this to the gecko tree climbers |
Answer: | This can be used but wasn't designed for Gecko climbers therefore operation & fit are not the best. A knee ascender is a better recommendation. |
Question: | Can this be used as knee ascender |
Answer: | Technically it can be, however we do not have a total knee ascender such as the HAAS that incorporates the Jet Step. You would have to create something that attaches the Jet Step in a way the HAAS or SAKA does & the liability would be on the user. |
Question: | Are the cams on the jet step stainless or aluminum |
Answer: | Aluminum |
Question: | Can this be attached to the gecko tree climbers |

User questions & answers
Question: | How can i attach this to my spur, so that i don't need the strap, can it be attached by getting a longer bolt for my spur and sharing that spot |
Answer: | Hello! That is not something that we suggest doing, as this is created to be a strap-onto foot ascender. For any particular issues like that, we suggest contacting the manufacturer of the item, Climbing Technology. |
Question: | whats the difference between the 69 dollar and the 73.59 ? one has a solid orange strap and the other is orange and white |
Answer: | I have the cheaper one. Works ok and I really dont like it. I quit using it after the teeth on the thing started pulling on the treads of my rope. I'm sure it'll work fine with another type of rope. If you're going to get one look into the knee ascender as well or a different way to get up. I have the L-scroll by petzel linked with a carabiner and a small pulley. Good luck |

User questions & answers
Question: | How much weight can this support |
Answer: | The maximum breaking strength is 4kN/890lb. |
Question: | Does it lock when you let go |
Answer: | It has to be anchored by both ends, which made this option coimplicated for a novice like me . Try looking at the Petzel "shunt" as another option. |
Question: | Description says 8-13mm, picture says 8-12mm |
Answer: | It is 8-13mm. I run 1/2" all the time |
Question: | Can you use this on your safety rope as a fall arrest?usually what do use with the ascender |
Answer: | No a chest descender isn't designed for primary life support when climbing or during a fall. It's main function is to help keep your climbing rope closely confind to your chest when you are using it in conjunction with a hand asenceder attached to a foot loop and a foot ascender. Using all 3 together will give you the advantage of quickly ascending a climbing rope using the rope walking technique. The main drawback is that you can't quickly descend in an emergency situation. You will need some extra gear such as a Petzl Rig to changeover when you need to descend. Watch this video to see an example: https://youtu.be/xHjFD1qjf1Y |
