Petzl NEOX® is a new-generation cam-assisted blocking belay device designed for sport climbing indoors and outdoors. It is optimized for lead climbing, making it easier to quickly feed slack while maintaining Petzl's assisted blocking technology.
The key innovation is the integrated wheel, which allows smoother and faster rope feeding to the lead climber.
When the climber falls or weights the system, the rope tightens, the wheel stops rotating and the cam pivots to pinch and block the rope.
This provides a more comfortable belaying experience while maintaining the standard safety technique of always keeping a hand on the brake side of the rope.
NEOX was developed primarily for lead climbing, where quick and smooth slack feeding is essential. It can also be used for top rope belaying.
The ergonomic handle allows easy rope release and controlled lowering. The handle and cam mechanism provide a 3:1 mechanical advantage, reducing the effort required to smoothly control descent.
All plastic components, including the handle, are made from recycled nylon.

Petzl NEOX is an excellent choice for climbers who mainly climb lead routes and want faster, smoother slack feeding than traditional belay devices. The integrated wheel reduces friction when paying out rope, while the cam-assisted blocking system improves comfort when catching falls.
Ideal for sport climbing, indoor training, outdoor crags and active lead climbers looking for a high-performance belay device. For beginner top-rope instruction, the Petzl GRIGRI+ may be more suitable due to its anti-panic function.
