Take your belay game to the next level. NEOX® is an assisted blocking belay device for the gym and the crag.
Ideal for lead climbing, it has an integrated wheel that allows you to smoothly and quickly pay out slack to the climber.
Its ergonomic handle provides comfortable descent control. It can be used with single ropes from 8.5 to 11 mm.

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, and 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 ropes
- Compatible with 8.5 to 11 mm dynamic single ropes and optimized for those 8.9 to 10.5 mm

Descent control
- Ergonomic handle allows you to easily unblock the rope and lower someone
- 3:1 mechanical advantage of the handled camming mechanism helps control rope feed on small-diameter ropes and requires less effort on the handle for large-diameter ropes
