Black Diamond

ATC - Alpine Guide

Alpinists reveled in rappelling, belaying, and using the ATC's guide mode so much that Black Diamond designed its classic belay device with a lighter, more compact device. Compared to the original ATC Guide, the Black Diamond ATC - Alpine Guide accommodates skinnier ropes so you can alpine climb with twin ropes a little easier. Apart from that, it features the same handling as the original, just for skinnier ropes.
