Product Code


The Petzl Reverso 4 Belay is an ultra-light multi-purpose belay/rappel device that regulates the amount of braking friction on the rope according to its diameter and condition. It is intuitive to use and features a Reverso mode for belaying one or two seconds with assisted braking. V-shaped friction channels with asymmetrical lateral grooves adapt the friction to the type of rope for better control (ARC technology: braking control for twin, half and single dynamic ropes).
