The Petzl Reverso 4 belay device is a versatile, ultra-light safety and descender with braking system for ropes of different diameters and characteristics.
This safety and descender device is ultra-light and intuitive to use. The V-shaped brake grooves and their asymmetrical side notches can be used to control the brake friction on the rope (brake system for dynamic half, twin and single ropes).
