Reverso 4 belay device 2018 Petzl

This multi-use belay device is ultralight (59 g, 25% less than the REVERSO 3) and intuitive to use. The "V" braking grooves, equipped with asymmetrical lateral grooves, modulate the braking on the rope for better control (ARC technology: braking control adapted to dynamic double, twin and single ropes). Reverso mode to ensure one or two seconds with assisted braking.

• Ultralight design:

- minimalist design,

- hot forged aluminum,

- Weight: 59g.

• A single device for all rope uses:

- effective braking on double and twin ropes ≥ 7.5 mm,

- effective braking on single ropes ≥ 8.9 mm,
