The ALPINE ATC-GUIDE BELAY DEVICE from mountain sports pioneers Black Diamond is a lightweight belay/rappel device optimized for ropes between 8.1 and 8.5mm.
Weighing only 73 grams, it's ideal for swift ascents and accommodates a range of rope sizes (6.9 to 9mm). The oval-ized anchor-hole facilitates easy rope handling, and the guide mode allows belaying one or two seconding climbers off an anchor.
With multiple friction modes, it provides optimal stopping power for lowering or rappelling.
