The Petzl Asap Lock fall arrester is designed to facilitate management during rope lifting. During normal use, the device moves freely along the rope without any manual intervention and follows the user in all their movements. In case of a shock or sudden movement, the fall arrester locks onto the rope and stops the user. The built-in locking function allows the user to immobilize the device to reduce the length of a fall. The connector makes the system resilient to falls when passing through intermediate anchors. The ASAP LOCK is used with an energy absorber for working at a distance from the rope. It is certified according to standards in the U.S., Europe, and Russia.
