The Petxl Neox is an assisted blocking belay device for indoor and outdoor climbing which can be used with single ropes from 8.5 to 11mm diameter. Ideal for lead climbing, it has an integrated wheel that allows smooth and quick pay out of slack to the climber.

 

Cam-assisted blocking creates 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. It also offers leeway for the brake-side hand position, regardless of the angle between the climber side and brake side of the rope. 

 

The ergonomic handle provides comfortable descent control and allows you to easily unblock the rope and lower someone. 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. 

 

All plastic components, including the handle, are made with recycled nylon.
