ULTRA-LIGHTWEIGHT: Weighing only 55g, the VERSO is the lightest belay device in the Petzl lineup; ideal for climbers prioritizing weight savings. VERSATILE COMPATIBILITY: Compatible with single ropes (8.5 to 11 mm), half ropes (7.1 to 9.2 mm), and twin ropes (6.9 to 9.2 mm). CONTROLLED BRAKING: Features V-shaped friction grooves with asymmetrical lateral channels that adapt the friction to the rope type for fluid control. ROPE PROTECTION: The rounded design of the rope slots limits wear and preserves the life of the rope for long-term durability. INTUITIVE USE: Diagrams for rope installation (belay and rappel modes) are engraved directly on the device for ease of use and safety checks.
