Assureur Ocun Bow - noir

Managing rope friction safely and efficiently is at the heart of every belay, and the Ocun Bow delivers precise control in a lightweight, hot-forged aluminium body. Its tube-style design with two friction modes adapts to a wide range of rope diameters, making it a dependable partner for rock climbing, mountaineering, and canyoning.

Tips

Always pair the Bow with a compatible locking carabiner, preferably with a round or oval cross-section to ensure smooth rope action. For high-friction mode, use the side with the additional grooves when belaying a heavier climber or using thinner ropes. Regularly inspect the device for sharp edges or excessive wear, especially after extended use on sandy or gritty ropes.
