The ASAP LOCK mobile fall arrester is designed to facilitate handling during rope ascents. In normal use, the device moves freely along the rope without any manual intervention and follows the user in all his/her movements. In the event of a shock load or sudden acceleration, 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 potential fall distance. The connection arm makes the system drop-resistant when passing intermediate anchors. The ASAP LOCK is used with an Asapsorber or Asapsorber Axess energy absorber to work at a distance from the rope. Arrests falls, slides, and uncontrolled descents Works on vertical or angled rope Locks on the rope even if grabbed during the fall Integrated locking function allows the user to immobilize the device in order to reduce the potential fall distance. In the event of a strong wind, this function also prevents the rope from being blown upward Mov
