Air Force One belay device is suitable for beginners or experienced climbers using small diameter ropes.
Belay Device for single ropes
The AIR FORCE 1 belay device can be used with single ropes of a diameter between 8,5 and 10,5mm. The V-groove runs smoothly enough to pay our slack easily, but also offers extra friction to improve rope braking while belaying and optimum energy absorption should the climber fall.
