Our most versatile belay/rappel device, the Black Diamond ATC-Guide is now even lighter thanks to windows machined through the body. We also enlarged the auto-block release hole to accept a small carabiner. Multiple friction modes provide the optimal amount of stopping power when lowering or rappelling, and the device's guide mode lets you belay one or two seconding climbers off an anchor.

Features:
• Multiple friction modes for belay and rappel
• Updated construction makes the device 10% lighter with improved rope handling.
• Now 80g
• Auto-block release hole accepts small carabiners
• Durable cable holds its shape and resists getting caught up
