Black Diamond ATC Guide Climbing Belay Device

BD Black Diamond ATC Guide is a belay device for climbing that accepts single, half, and twin ropes with a diameter ranging from 8.1 to 11 mm.

The updated version from 2019 now sees the ATC-Guide lightened by 10% with a weight of only 80 g. Additionally, the holes have been improved and made more oval to allow the rope to slide better without damaging it too much.

In addition to the traditional belaying method, one or two seconds can also be belayed, and rappelling on double rope can be done.
