The Petzl ASAP Lock mobile fall arrester with locking function is the market leading back-up device for rope access systems. At moderate speeds, the locking wheel runs freely in both directions, following the user. However, when a rapid movement occurs, the wheel stops, pinching the rope between the wheel and the ASAP frame, thus stopping the user. The ASAP can also be used as a primary belay device in a fall arrest system.
Warning: the Petzl ASAP Lock is a directional device and locks in only one direction. Positioning the device upside down on the rope could lead to death.
Use the Petzl ASAP Lock on low stretch conforming to EN 1891 Type A ropes with a diameter between 10mm-13mm
