Petzl Neox Belay Device

Belay device with cam-assisted blocking, optimized for lead climbing
+ 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
+ Cam-assisted blocking for a more comfortable belay; when the climber falls or weights the system, the rope tightens, the wheel stops spinning, the cam pivots to pinch and block the rope

Easy to use
+ Easy to install the rope with diagram engraved on the belay device
+ 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
+ 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 8.5-11mm dynamic single ropes and optimized for those from 8.9-10.5mm
