Self-braking Belay Device

Device for belaying a leader or a second and for single rope descents.

Features:

• Self-braking system: if the rope suddenly comes under tension (e.g. in a fall), the cam pivots to pinch the rope, thus helping the belayer stop the climber's fall.
• Usage is similar to that of conventional belay devices:
• Giving/taking slack is done by using both hands to slide the rope through the device,
• Falls are held by holding the free end of the rope,
• For lowering and rappelling, the rate of descent is controlled by the hand holding the free end of the rope (the rope is released with the handle).
• For ropes of diameters from 10 to 11 mm.
• 225 g.
