Technical Details

I acquired my Climbing Technology Be↗Up from Expé-Spelemat in2015.

The Climbing Technology Be↗Up is a notched belay tube. It is forged from aluminum alloy, folded in the process, and then soft anodized. The ends of the fold are pinned together with a 5 mm. stainless steel pin. Mine is 41 mm. long, 80 mm. wide, 90 mm. high, and weighs 86 g. The slots are 33 mm. long and 13 mm. wide. Each slot has two shallow grooves on each side. The top of the Omega oval carabiner that I use for comparing belay tubes sits 36 mm. below the ends of the slots.

One side is printed "MADE IN ITALY," a rigging illustration (for a lead climber), with the Climbing Technologies CT logo, "BE↗UP, and "climbing technology. The other side is printed with a rigging illustration (for top-roping), "0215," "EN15151-2," "UIAA", a book-with-an-"i" icon, "ROPE EN 892", "①Ø 8.5÷10.5 mm,"and "½∞Ø 7.3÷8 mm" where the "½" and "∞" are in circles, a three-ring icon, and "ANCHOR."

Comments

The Be↗Up's unique shape gives it much deeper slots without increasing the mass by much. This in itself is not a particular advantage. The open construction provides more surface area for heat dissipation, but the lower mass gives less ability to absorb heat. Like all belay tubes, the Be↗Up can get quite hot when used as a rappel device.

The folded construction also provides a natural eye for attaching the Be↗Up to the anchor.

The slots do not seem to provide the effective braking that the slots on the Double V-Row provide.

I acquired my Climbing Technology Double from Lior Porian in 2015.

The Double is a standard belay tube. Mine is 47 mm. long, 56 mm. wide, 96 mm. high, and weighs 62 g. It is forged from aluminum alloy and then soft anodized. It has two slots and a stiff plastic covered cable keeper. The slots are 31 mm. long and 15 mm. wide. The top of the Omega oval carabiner that I use for comparing belay tubes sits 14 mm. below the ends of the slots.

One side is screened with the Climbing Technologies CT logo, the UIAA logo, "Italy," "0114-2014," and a rigging illustration.

Comments

The Double is typical of the lightweight belaying devices that are so popular among climbers. Like all similar devices, it can overheat on long rappels, but for belaying with 11 mm rope, it works fine. Rigging is simple: insert a bight of rope and clip it with a suitably anchored carabiner, making sure that the rope is not running over the keeper. Two-rope rigging is similar. On thinner ropes, adding another carabiner helps. My biggest complaint, common to most of these devices, is that it doesn't give me enough friction when rappelling with a heavy load on fast 9 mm. rope.

Technical Details

I acquired my Climbing Technology Double V-Row from Lior Porian in 2015.

The Double V-Row is a notched belay tube. It is forged from aluminum alloy and then hard anodized. It has two slots with a deep V-groove at one end of each slot. Mine is 48 mm. long, 60 mm. wide, 109 mm. high, and weighs 74 g. The slots are 33 mm. long and 15 mm. wide. The top of the Omega oval carabiner that I use for comparing belay tubes sits 13 mm. below the ends of the slots.

One side is screened with the Climbing Technologies CT logo, a rigging illustration, "Italy," "0111," and the UIAA logo.

The following are essentially the same device:

I like this design enough to give it three stars:

These are just like many other devices except for one little difference, but that difference makes any of these a much better device than those others. The special feature is the teeth. First of all, if you don't need them, turn the device 180 degrees and they are out of the way. On the other hand, if you want more friction, then these teeth provide it. This is the only device design of this size and weight that I feel comfortable rappelling my 9 mm. haul line on, with the others, I never really felt completely in control (to be fair, I haven't tried this on the the Omega Pacific SBG or the Simond Cubik). The extra control is well worth carrying the extra 15 or 20 grams. One caution: like all belay tubes and tubers, these can still get very hot on rappels.

I borrowed the following paragraphs from Trango's web site, although they should apply to any of the devices in the table:

Jaws stops better than most belay/rappel devices. The addition of the V notches really grabs the rope, assisting in slowing down the fall. In lab tests using a UIAA drop tower, an 11 mm. rope, an 80-kg weight with a fall factor of 1.2, and a clutch holding the rope with a 50-lbf slip threshold, we found the following results:

 Pyramid/ATC/Tuber style devices  16" - 20" slip, no rope damage
 GriGri  1" - 3" slip, no rope damage
 Jaws  6" - 8" slip, no rope damage

Jaws allows you to adjust the rope friction during a rappel. By flipping the rope out of the notches and over the side plates at the start of a long rappel, you can reduce the friction the device gives you at the start. When the rappel begins to speed up as you get closer to the ground, flip the ropes back into the notches to slow it down.

You must rig Jaws correctly. It's not symmetrical so you need to be sure the notches are on the brake hand side of the rope, not on the side which goes to the leader. Also, because of the additional friction provided by the device you'll find that the beginnings of long rappels can be a bit jerky. The solution is to allow rope to slide through by varying the angle of your brake hand rather than just letting rope slip through. On low angle slab rappels, turn Jaws around so the notches are on the anchor side and your brake hand is on the smooth side.
