The Petzl Universo Belay system combines a VERSO belay device and an ATTACHE 3D carabiner all held in optimal position by a sliding connection piece. The UNIVERSO is a complete and lightweight belay system that is particularly comfortable and efficient to use on all rope diameters. The exclusive sliding connection piece allows the VERSO belay device to remain in position and the ATTACHE 3D carabiner to work along its major axis. The connection piece also limits the risk of dropping the belay device during rope maneuvers and reduces the risk of being burnt by the belay device when removing it from the rope. The system is easily reversed for right or left and is a great single device for all rope types. This rope friendly belay device allows for smooth belaying and rope handling, it does not twist the rope and keeps the two strands separate. The asymmetrically grooved sidewalls offer increased breaking power while also providing smooth sliding when taking up slack.
