Black Diamond

ATC Belay Device

They say imitation is the most sincere form of flattery, which is why you won't find the Black Diamond ATC griping about the wannabes. Built to handle ropes ranging in diameter from 7.7mm to 11mm, this simple but functional device handles belaying and rappelling with kink-free ease. And weighing in at a slim 60-grams, it's a must-have addition to your harness.
