Assisted Locking Belay Devices have innovated single rope belay methodology. Assisted locking belay devices will/should lock when a fall is taken. They may be used to ascend rope or ladder during a zipline launch. They are great for zipline launch deck where participants or instructors are belaying. Caution should be taken to back up novice belayers when they begin to lower the zipliner. Some of these belay devices are not recommended for beginner climbers and belayers. These assisted lock belay devices are best for reducing shock loads to the belay system when holding falls that generate extremely high loads.
