The Petzl ASAP LOCK mobile fall arrester is designed to facilitate handling during rope ascents. In normal use, the climbing rope lock moves freely along the rope without any manual intervention and follows the user in all his/her movements. In case of shock or sudden movement, the fall arrester locks on the rope and stops the user. The integrated locking function allows the user to immobilize the device in order to reduce the length of a fall. The connection arm makes the system drop-resistant when passing intermediate anchors. The Petzl ASAP LOCK is used with an energy absorber to work at a distance from the rope. It is certified to US, European, and Russian standards.
