I lost my nano 8 and have been looking for a replacement everywhere. If anyone happens to see this and have one to sell let me know :)))

Hi Steph,
Unfortunately, since it's been discontinued, I would say you might have luck contacting the vendor directly to see if they have any extras for warranty they might be willing to part with for sale.

Answer this question:
Extremely useful device for abseiling and belaying when using very narrow 6-7.5mm ropes; particularly for skitouring, mountaineering and glacier travel. You MUST spend time testing it and getting used to it. A backup Prussik is highly recommended when single-roping. I also notice that the Mammut setup doesn't quite give you enough friction single roping, but putting the rope back through the 'crab you have the Nano8 on forces the rope to drag across itself, adding more friction. Overall extremely highly recommended. See photos of me with mine here: https://twitter.com/jamesmadelin/status/1115232494939529216

I have not been able to find any available technical information indicating how small of diameter ropes this device is designed to work with. Will the Nano Eight work with twin 6.0 mm rappel ropes?

Hi Nat, it works well with 6mm ropes. Always test in a safe place with a new rope before jumping on something big!

Mammut publishes the diameter range on the actual device, not to mention in their downloadable manual too! They list it as suitable for 6 - 7.5mm ropes. I own one, for use with the super-slippery 6mm Petzl RAD line. It works incredibly well, though you MUST spend time testing it and getting used to it. A backup Prussik is highly recommended when single-roping. I also notice that the Mammut setup doesn't quite give you enough friction single roping, but putting the rope back through the 'crab you have the Nano8 on forces the rope to drag across itself, adding more friction. Overall extremely highly recommended for the specialised use of small diameter rope abseil and belay. See photos of this here: https://twitter.com/jamesmadelin/status/1115232494939529216
