A single rope belay device which when a climber falls, creates a large amount of braking assistance. When a climber falls the belay carabiner is pulled upwards into the notch on the Jul 2, squeezing the rope to making high performance braking. The design of the Jul 2 makes paying rope out easier to lead climbers if the device is used in the "open" position with the thumb, it further assists belayers with lead falls. Easy to use, so suitable for both beginners and experienced climbers, this lightweight device is perfect for anyone's pack!
