The Air Force 1 works with single ropes of any diameter. It fulfills the needs of beginner climbers using a classic rope as well as advanced climbers using thinner ropes.
It reduces abrasion to the rope. The V-groove offers extra friction to improve rope braking while belaying and optimum energy absorption when catching a leaders fall, yet provides enough smoothness to pay out slack easily. The wide, straight groove offers edge-free running of the rope.
Reduces abrasion to the rope. Braking force adapts to the rope diameter. Individual number. Compatible with rope diameters from 8.5 mm to 10,5 mm.
