Be Up


My vote: None ( 5.3 avg )


Insurer / Multipurpose descender with innovative and compact design ( registered design ), suitable for use with double ropes, ropes and twins entire rope, climbing, climbing routes with sports pitches and trad. Intuitive and easy to use is equipped with modular braking system to optimize braking with each type of rope and allows independent recovery and self-locking of seconds.

It allows extremely versatile:

the insurance first climber effectively. The unique body design allows to give the rope smoothly, quickly and smoothly;
during securing a lead climber on multi-pitch routes with two strings, to give a rope while the other is blocked, this maneuver makes Up Be unique;
the effective braking and modular cords through the grooves "V", specially designed for a best control of the braking during the arrest of a flight, double rope and recovery of seconds;
the independent recovery and self-locking of one or two seconds ( mode guides ). The special geometry of the integrated attack and ring device in the body, allow you to effectively recover one or two seconds with half ropes and twin ropes ≥ 7.3 mm dia. It also allows to recover a second, while the other is hung to the gear;
the release and the dropping of a second progressive live even in a vacuum, without effort, with half ropes and twin ropes ≥ 7.3 mm dia. This maneuver makes it Up Be one of a kind and is carried out by inserting into the hole is a simple unlocking carabiner HMS;
the rapid transition from recovery mode ( < > mode guides ) insurance of the first, in scaled to alternate shooting;
The abseiling keeping separate ropes. The grooves "V" allow to control effectively the rate of descent, without twisting the ropes.
Construction details / specifications:

form lightened and extremely functional, for a good yield of use;
hot-forged body, which gives an excellent resistance;
integrated retainer ring in the body, easily identifiable in order to prevent the risk of hooking errors;
cable of plasticized steel, to make unmissable tool and limit the movement when being secured.

Device Type


The most commonly used belay type also called an “ATC” or “tuber.” Other than a distinction between other belay device types, “Tube” is a rarely used term, most climbers just assume you're talking about this style when they refer to your "belay device."

Tube belay device example

Figure 8

Mostly used in rescue, canyoneering, tactical, work safety, or by old school climbers and rappellers. One reason they went out of popularity with recreational climbers is because they tend to create twists in the rope.

Brake Assist

These devices assist in stopping the rope when a climber falls or hangs on the rope.

Brake Assist belay device example

Often referred to as “auto-blocking” but that’s not the official terminology because no belay device should be assumed to work automatically by itself, even if it feels like it does (or does most the time).


When simplicity is a must, or you started climbing before Tubers were the norm. Bonus: They tend to be very light weight.

Plate belay device example


For rappelling, not for belaying a lead climber or top-roping.

Belay Brake Assist

Belay Brake Assist

This is when the belay device significantly reduces the amount of holding power the belayer must exert to stop a fall and hold a climber.

This is also called "assisted-braking" as the device must hold a significant amount of the climber’s weight; this term does not include friction-adding "teeth" found on some tube style belay devices.

Confusingly referred to as “auto-blocking” or “auto-locking” these terms wrongly imply the device will always, automatically, stop a fall or hold a climber even if the belayer/rappeller is hands-free. These devices are not meant to be used without a hand on the braking side of the rope; the belayers/rapppeller brake hand should always be on the brake rope.

Worth Considering

Most of the mechanical brake assist devices only hold a single strand of rope and are not capable of double-strand rappelling (the most common method of rappel).

Rope Options 1 or 2 ropes
Guide Mode

Guide Mode

This is when you belay directly off the anchor instead of your harness. Guide mode is helpful if you climb outdoors a lot because it reduces the holding power required from the belayer. When your partner falls or rests, the weight of the climber is held mostly by the anchor and the belay device.

Tubers and Plates

When belaying in "guide mode," the tubers and plates turn auto-blocking. During a fall, the climbing rope pinches the slack rope, completely stopping the movement of either rope. A common guide mode setup shown below.

A double rope tubular device guide mode example

Mechanical Brake Assist Devices

There is no difference in the functionality of the device. A brake-hand should always be on the rope to ensure the climber is caught in the case of a fall. A common guide mode setup shown below.

Where guide mode is used

  • multi-pitch sport or trad climbs
  • single-pitch where you need to bring up a follower (say for a walk-off)

Teeth are only seen on tube devices. They add friction that helps grip the rope for more belaying control.

This is helpful for belaying heavier climbers. Teeth are becoming standard on new tube devices.

The belay device teeth are shown in the red circle

Worth Considering

Teeth do wear out. You can limit wear by rappelling on the side without teeth (if you don’t need the extra friction). Once they’re worn, you’ll still have a usable belay device, just less friction.

Rope Range (mm)

Rope Range (mm)

The range of rope diameters, in millimeters, that the manufacturer/brand specifies can safely be used.

This is the best case scenario and does not necessarily take into consideration that certified ropes have a tolerance of +/- .3 mm.

Recently, manufacturers have started to add an "optimized" rope range -- this is the range that will result in the nicest handling of the belay device.

7.3 mm  - 10.5 mm ­­
single: 8.5 - 10.5 twin/half: 7.3 - 9.0


The main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries.

To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process.
