Ascender Type

Ascender Type


Hand

Hand ascenders are used to manually ascend rope by pulling down with hands. They always have handles and are typically made in left and right hand versions.


Chest/Compact/Basic

Chest, Compact and Basic ascenders are often used in conjunction with other rigging or devices for ascending rope or progress capture. Their shape is made to be pulled down on and they have lower holes for attachment, though they aren’t as comfortable to use as hand ascenders. The upper holes also allow them to be used as a trailing backup.


Backup/Rope Grab

Backup or Rope Grab ascenders are used as emergency backups and efficiency devices in hauling situations. They are usually trailed behind a climber via a sling when ascending a fixed line, or to give mechanical hold on a rope when pulling on a weighted line.


Foot

Foot ascenders allow direct attachment of the foot to a rope and are most often used in arboriculture and work at height situations where the only thing to climb is a rope. They typically do not have holes for attachment of carabiners and do not function as safety backups.

Backup / Rope Grab / Capture Pulley
Tooth Type

Tooth Type

Toothed

The teeth on toothed ascenders are usually conical and sharp. They are designed to physically bite into the sheath of the rope. Toothed ascenders are the most common for devices made to climb rope.


Ridged

Ridged tooth ascenders clamp on the rope with flat, jagged teeth that are the width of the device. The teeth do not bite into the rope sheath but rather clamp it with the force of the triangular shape of the teeth. Ridged teeth are usually seen on backup ascenders but do also appear on foot, chest and pulley capture devices.


Smooth

Very few toothless ascenders exist but some manufacturers tout toothless as a benefit of reducing wear on ropes. This style is mostly found on rope clamp/hauling devices.

Toothed
Bottom Holes

Bottom Holes

Bottom Holes

Manufacturers provide holes for attaching carabiners and equipment to the bottom of ascenders. Some of these are made to accept one or more carabiners, while others are designed to accept one carabiner and a quick link (or maillon) for semi-permanently attaching a loop or ladder. Usually only ascenders made to operate attached to or above a climber have lower attachment holes. This option only applies to devices with both Upper and Lower holes.


Not applicable for this ascender type
Handedness

Handedness

Hands

Hand ascenders are made with handles designed to be held and operated by the left or the right hand, however there are a few that have 2 handles designed to be used by both hands.


Feet

Foot Ascenders are usually made to attach to a specific foot, left or right, or may be either/or.


Other

Most other types tend to not have a preference for handling or are not made to be pulled on without additional carabiners, ladders or materials and are considered both left and right handed.

Features

Features

Certified Pulley

Some rope grab devices function as a weight certified pulley when hung from an anchor in a hauling situation. These pulleys ease efficiency and movement of the rope when under load but in order to be safely used to haul large weights and humans, these devices must pass extra certification (EN 12278/UIAA). Note: Not all devices with rolling surfaces/pulleys have been certified to be used as a pulley. Certified Pulleys should not be confused with Built-in Rollers which are not rated to hold weight.

Integrated Belay

These ascenders have a built in single slot for passing the rope through which allows the ascender to be used as a belay device in a controlled descent on a single rope. While designed to allow a climber to transition from ascending to descending on the same rope, this feature can also be used to lower out a climber or load and could technically be used to belay in a pinch.


Built-in Roller

A built-in roller can be helpful when working at height or ascending a rope with a progress capture device. It can help to add efficiency and give mechanical advantage by redirecting the rope above the climber. This can also be helpful during hauling situations where continual dropping and lifting of a climber’s weight is necessary. These rollers are not rated as a piece of PPE and should not be confused with Certified Pulleys which are tested to hold a climber’s weight or heavier loads.


Mid Attachment Hole

A middle hole that a carabiner can fit through. This is particularly helpful for higher placement of a carabiner pulley setup.


Works on Webbing

Some ridged toothed ascenders are designed to be used on flat webbing as well as ropes. Their intent is not necessarily for vertically scaling webbing, but rather for clamping backups and positioning along webbing, which can be particularly useful during rescue and work at height situations.

Rope Range

Rope Range

Certified Devices

All ascenders and rope grab devices that have been certified by the EN or UIAA are required to list a rope range. This range is not a specification of the test, but rather the cert is an acknowledgement of the device functioning correctly with that size rope. Essentially, a manufacturer can seek to certify a device to work with any size of rope they want, and if it passes the certification at that size then they are required to print it on the device.

The most common rope ranges tested for EN567 are in the 8-13mm range.

The most common ranges for EN 12841A/B are 10-13mm.


Non-certified Devices

Devices that carry no certification may or may not have specified rope ranges. Foot ascenders and other rope grabs that are not made to be used as PPE (Personal Protective Equipment) do not have a standard operating range of rope sizes and should be looked at more closely to determine the manufacturers recommendation for their use.

Rope ranges for these devices can vary wildly but are often in the 10-13mm range.

8 - 11mm EN 567 (as a rope clamp)
Certification

Certification

EN 567:2013 (UIAA 126)

This is a static certification. It denotes a static holding power of 4kN and does NOT include testing the device to arrest a fall of any kind. EN 567 is described as a rope clamp device and is tested ONLY to be used to capture progress in one direction on a rope or webbing.


EN 12841:2006

This is a certification in three types: A, B & C.

12841:A (12841/A) is certified and tested to hold a static pull of up to 15kN AND a dynamic fall up to 6kN.
12841:B (12841/B) is certified and tested to hold a static pull of 4kN and must catch and hold 100kg then be pulled and held at 3kN without failing.
12841:C is a rating for descending devices and does not apply here.


EN 12278:2017 (UIAA 127)

This certification applies only to devices with pulleys. It certifies that the pulley itself rolls correctly under a load of 2kN and does not fail at or below a load of 15kN.


Uses

In general, EN 567 can be thought of as progress capture and a safety backup in static situations, such as being trailed along a fixed line. When used for safety in a more dynamic situation like toprope soloing, they should always be used with backup devices which are certified to catch a dynamic load such as a device with the 12841:A certification.

Devices that are 12841:B are more complicated. While they are tested to catch a dynamic load they are not tested to ensure that force doesn't exceed 6kN, which means they may lock in a way that transmits a greater amount of force from a fall to the anchor. Since their holding power is not tested beyond 3kN after this fall arrest, they should never be relied upon as the sole safety device to catch a fall.

Devices with pulleys rated EN 12278 or UIAA are most often capture pulleys meant to be utilized as hauling devices. The certification denotes that they are safe for heavy loads like multiple humans and haulbags which are often much more than 100kg (220 pounds). If an ascender has a roller and does not have this cert, it has not been tested to hold this much weight so extreme caution should be used when utilizing it in this fashion.


It is important to note that devices often have multiple certifications. For example a device may be tested to hold EN 567 forces AND be certified to pass the 12841:A standard. If purchasing any devices in the ascender category we highly recommend understanding ALL of your needs and the forces they can generate and being aware of a device's limitations before trusting your or someone else’s life to it.

Note: We only include current standards. This means certifications like EN 567:1997 (year 1997 vs year 2013) are outdated and not included.

Perfect to use in your small rescue kit with a carabinerpully. Perfect gift for the climber have all he need but need somthing cool. DO you need one if you have a prusic, NO but is it fun to have Yes

No reason not to carry one

Pros
Tiny
Low cost
Easy to attach to ropes
Survives falling 200-ft without damage
Familiarity
I’ve used it a few of times

No reason no to carry one-- it's tiny, cheap, and very useful.

Drop your primary ascender? Use this in its place.
Need to haul? It bites better than a prussik.
Emergency and a person needs to be hauled? Yup, does that too and it is more reliable in slippery conditions than a prussik.

It’s the side-piece

Pros
It’s light as heck
It’s the size of a very large grape
Cons
It’s small enough to lose/drop

I prefer gen-1 over gen-2 Tiblocs

Don't listen to what they tell you, size matters. The Tibloc is a fantastic emergency ascender, but is small enough to lose when playing with it—which would be a huge dissapointment. Your friends might make fun of you for having such a small piece of gear.

WeighMyRack Gear Review no rating given just a review

When we check the WeighMyRack database for the most wanted and owned Ascenders by WeighMyRack users we find no hand ascenders in the top 3, but we do find the top 3 models of rope grab / capture pulley’s are…

Climbing Gear Reviews UK no rating given just a review

Though marginally more bulky than the original the new TIBLOC sits perfectly alongside my MICRO TRAXION on a pulley carabiner as my ‘hope I never have to use it’ crevasse rescue kit. As you can see from the photos the new TIBLOC is actually lighter than a medium length prusik! So; lighter than a prusik cord (won’t abrade/degrade in UV either), grips icy ropes better, lighter than the old TIBLOC, and can be used to increase security simul climbing! If you travel in crevassed terrain or may ever need to rescue or self rescue just buy one (and get trained!).
