3:1 mechanical advantage from the handle and camming mechanism helps reduce the amount of effort needed to smoothly control the rate of descent, regardless of rope diameter
Cam-assisted blocking for a more comfortable belay: when the climber falls or weights the system, the rope tightens, the wheel stops spinning, and the cam pivots to pinch and block the rope
Cam-assisted blocking offers leeway for the brake-side hand position, regardless of the angle between the climber side and brake side of the rope
Compatible with 8.5 to 11 mm dynamic single ropes and optimized for those 8.9 to 10.5 mm
Easy to install the rope with diagram engraved on the belay device
Eco-design: all plastic components, including the handle, are made with recycled nylon
Ergonomic handle allows you to easily unblock the rope and lower someone
Feeding slack and catching falls are accomplished using techniques standard to all Petzl belay devices, always keeping a hand on the brake side of the rope
For belaying both lead and top rope climbers
Optimized for lead climbing, it has an integrated wheel that allows you to smoothly and quickly pay out slack to the climber
