Technical Details

I acquired my Fusion from Yi-tien Tuan in 2008.

The Fusion is a plain belay tube. It is forged from aluminum alloy and soft anodized. Mine is 51 mm. long, 46 mm. wide, 100 mm. high, and weighs 61 g. The Fusion has slots, each is 33 mm. long and 13 mm. wide. The top of the Omega oval carabiner that I use for comparing belay tubes sits 16 mm. below the top of the slots.

One side of my Fusion is marked with the Fusion logo, while the other a rigging icons.

Comments

The Fusion is one of the following closely-related belay tubes, all called "ATCs" after the original Black Diamond Air Traffic Controller:

Each of these is 54±3 mm. long, 46±1 mm. wide, and weighs 59±9 g. Their slots are all 32±1 mm. long and 14±1 mm. wide. They all have plastic-covered cable keepers.

The Black Diamond ATC was the first of these to appear, by many years. The basic design evolved and similar devices appeared from others.

The ATC is a lightweight, popular belaying device among climbers. 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 is that none of these give me enough friction when rappelling with a heavy load on fast 9 mm. rope. I also prefer more friction while belaying, unless my partner is particularly lightweight. For these reasons, I prefer using a Trango Jaws or one of its equivalents.

Any of these will overheat badly on long rappels. Overheating is not an issue when belaying, but can be a concern when lowering someone more than a short distance.

There are four different shell styles in use::

  1. There is a small shelf at each end of the shell with a hole passing through it. The keeper cable has a crimp at the ends, which are visible from the top of the device.
  2. There is a small shelf at each end of the shell with a blind hole in the bottom. The keeper cable enters the holes, and is staked in place. The stake dimples are visible at the ends of the device.
  3. There is a bulge at each end of the shell with a blind hole in the bottom. The keeper cable enters the holes, and is staked in place. The stake dimples are visible at the ends of the device.
  4. Like style III, but the shell has a shallow valley above the bulge.

The differences between the styles are cosmetic rather than functional.

None of the keepers-to-shell are strong enough to support body weight, so don't be stupid enough to rely on a keeper to protect you.

There are also several different diameter keeper cables used on these. Cable keepers are a compromise between a cord that stows easily but tends to get tangled in use, and a rigid rod that stands up to the rope running over it (by accident, of course). I prefer a stiff keeper, but any of these are stiff enough to be used without significant problems.

Technical Details

I acquired my Fusion Neo-Sat from Hanny Piltz in 2011.

The Fusion Neo-Sat is a notched belay tube. It is *forged from aluminum alloy and then soft anodized. Mine is 55 mm. long, 43 mm. wide, 97 mm. high, and weighs 61 g. The slots are 34 mm. long and 15 mm. wide. The top of the Omega oval carabiner that I use for comparing belay tubes sits 16 mm. below the ends of the slots. The plastic covered cable keeper is moderately stiff.

One side is printed with two rigging icons, "FUSION," and "CA USA."

Each of these is 54±1 mm. long and 45±1 mm. wide, and has a weight in the 60±7 g. range. Their slots are all 35 mm. long and 16 mm. wide.

The shallow V-notches used in this design do not seem to be very effective at increasing the braking force. The notches do not have the narrow angle found on the Trango Jaws and its equivalents, so they do not create the same wedging action. Spreading the friction helps with heat dissipation, but like all belay tubes, these can get quite hot when used for rappelling.
