Every belay device rolled into one.

Roll an auto-locking belay plate, a figure 8, and a canyoneering descender into one, and you have the Sterling ATS. Use the ATS in plate mode to belay a leader, or attach it directly to the anchor to belay the second with auto-locking functionality. Sterling added a second hole for use as a release mechanism if a following climber falls and has to be lowered. When it comes time to descend, you can either use the ATS as a traditional plate or as a figure 8 device. Either way, you can use the four horns to add friction or tie off a descent as needed, which you'll really appreciate on long raps.

  • Functions as an auto-locking device when belaying directly off the anchor
  • Can belay two followers at the same time
  • Device has a second hole for use in lowering a fallen follower
  • Works as a plate or figure 8 device when rappelling
  • Horns add friction to help you control long descents
  • Easy to tie off during rappels
  • Note: read the instruction manual carefully before using this device

this is listed for SAR use, so it will work with a 1/2inch static rope?

love it, but...

I've been playing around with it and so far has been great. I haven't taken it out yet, but all the uses and instructions are great...only problem is the hole for the caribener is too small. none of my black diamond locking caribiners fit. the only one i have that works is a none locking.

the best of everything

The ATS is fantastic. You can tie it off like a Piranha. It is small and simple like an ATC. You can flip the curvature of the device to vary the friction levels, which comes in very handy. You can also use it as an auto block, which I don't believe you can do with an 8, Piranha, or ATC. Rappel racks are probably the smoothest overall, but they are too bulky and heavy for backpacking.

You can auto lock with an 8 easier than with this device, however this one is more versatile.

Over my forty years of climbing I have tried many different types of devices, and this is the best one I have ever had. This device is the Leatherman’s of devices, so much functionality in one device. It is the only thing I carry on my harness anymore.

Rappelling: I really like the deferent friction modes as you are rappelling. When I get to a steeper part of the cliff or an over hang I just put the rope over the hyper horns and have a very smooth and enjoyable trip down, kid of like down shifting my Ford pickup.

It dose take a large round stock carabiner, to have a smooth ride. I tried one of the small Mammut Element key lock screw gate carabiner, and a standards SMC, they have to tight of edges. The Petzl M35 Sl Pear – shaped carabiner works very well.

Belaying: I found placing the curve towards the belay carbiner, worked better than the curve away from the belay carabiner. When the curve was away from the belay carabiner, it had a tendency to stick. But with the curve towards the belay carabiner it floated better, but there was still plenty of breaking power. It kind of handles like a stitch plate, so having very tight belays was a little harder they a traditional ATC, but facing the large hole end on the top side of the rope made a handle that made it very easy to pull it away from the belay carabineer. The ATS it the best lead belay device, I have ever used feeding the rope out was very smooth, and a lot quicker than a traditional ATC type device.

Auto Belay: This is the best auto belay device I have ever used. Over the past few years I have tried, the B53, Reverso, Reverso 2, Mammut Vader Alpine, Black Dimond ATC guide, and non of them works as well at the ATS. But the key is to use a small carabiners so the device can hinge in the small hole. Connection the break carabiner can be a little difficult, you need a large long carabiner. The Petzl M35 was just not long enough, I used a old very large round stock parabiner. Like the Rappelling, a round stock carabiner works the best.
The best think about it is you can easily feed the rope out, by pulling on the large hole handle, but it still auto breaks. No other device I have used made it so easy to feed the rope out, when it was not under load.

Love my ATS almost more than my Ford pickup
