PETZL NEOX Belay Device with Cam-Assisted Blocking for Lead Climbing - Orange

Upgrade your belay practice with PETZL NEOX

Take your belay game to the next level. The PETZL NEOX is an assisted blocking belay device designed for both the gym and the crag. Built around an integrated wheel, it lets you smoothly and quickly pay out slack to the climber while maintaining secure control when a fall occurs. The orange finish adds high visibility on busy routes, helping you keep focus on the climber and the rope.

How the NEOX works in practice

Its stainless steel wheel rotates freely while you feed or take slack. When the rope is weighted, the wheel stops and the cam engages to block the rope, enabling confident handling during belays and transitions. This combination of motion and restraint supports steady rhythm, even when the pace changes mid-climb.

• GIVE SLACK EFFICIENTLY: The wheel design reduces the effort needed to feed slack, keeping the belay fluid on long or complex routes.
• CAM-ASSISTED BLOCKING: An internal cam pivots to clamp the rope as soon as weight is detected, helping you manage falls with less brake-hand fatigue.

Descent control and easing belayer fatigue

Lowering is smooth and controlled thanks to a 3:1 mechanical advantage, and the ergonomic handle provides a natural, comfortable grip for progressive descents. These thoughtful ergonomics make repeated belays feel more manageable during long sessions.

• DESCENT CONTROL W/ 3:1 MECHANICAL ADVANTAGE: A controlled, progressive descent supports steady communication with the climber.
• ERGONOMIC HANDLING: The handle design supports stable operation during dynamic moves or extended belay days.

Rope compatibility and practical usage

Use the NEOX with single ropes in the 8.5–11 mm range, a common size in many gyms and climbing areas. Its compact form and reliable blocking make it suitable for lead routes, training days, and mixed indoor/outdoor setups.

Performance in different settings

In busy gym environments, the smooth slack control helps you maintain rhythm as routes change. On crags, the compact profile keeps your belay tidy and secure at belays that require quick adjustments. Regular inspection and proper usage enhance reliability across sessions.

Why climbers choose NEOX

Beyond the blocking action, the NEOX design reduces fatigue in high-volume belaying scenarios, helps maintain focus, and supports safer movement when transitions happen in gyms or crags. The orange color enhances visibility on rock and in indoor spaces, making it easier to spot in cluttered setups.
