The Black Diamond Alpine ATC-Guide is a compact, 73 g version of the ATC-Guide belay and rappel device. It is sized for thin ropes from 6.9 to 9 mm.

What it's for

A tube style belay and rappel device for alpine climbs where you carry thin ropes and want less weight on the harness. You can belay a leader, rappel on one or two strands, and belay one or two followers directly off the anchor in guide mode.

How it works

Friction modes: the device offers more than one friction setting for belaying and rappelling, so you can match the grip to your rope and load

Guide mode: hung from the anchor, the device locks the rope when a follower weights it. It works with one or two ropes

Release hole: the hole used to release a loaded device in guide mode accepts a small carabiner

Cable: a stiff cable keeps its shape and resists getting pulled in between the ropes

Compatibility

• Rope diameter: 6.9 to 9 mm
• Works with thin ropes most smoothly: 8.1 to 8.5 mm
• Does not fit: ropes thicker than 9 mm. Use a standard ATC-Guide for those
• How to check yours: read the diameter on your rope's end label or hang tag and make sure it falls in the range above
• You will need: a locking carabiner for belaying, and a second locking carabiner for guide mode
