Black Diamond ATC Belay/Rappel Device

The Black Diamond ATC is the classic tube-style belay and rappel device, a simple, minimalist design that has been a go-to for climbers of every level for years. It handles single ropes from 7.7 to 11 mm and weighs just 60 grams, so it disappears on your harness until you need it.

The trade-off of a tube device is that it does not offer assisted braking. Your brake hand does all the work, which is exactly why it is such a good tool for learning the fundamentals and for rappelling smoothly on a single rope.

It is for gym climbers buying their first kit, sport and trad climbers who want a light and reliable backup, and anyone who wants one device that belays and rappels. Climbers who want assisted braking for long projecting sessions may want to pair it with an assisted device for the gym.

The minimalist build is durable in all conditions, with nothing to adjust and very little to wear out. Pair it with a locking carabiner and it is ready to go, whether you are at the crag or on the wall at the gym.

We think the ATC belongs on every harness, the simple, trusty device that teaches good habits and keeps working for seasons.
