Petzl's ASAP fall-arrest device works on vertical or angled safety rope by allowing you to move freely up or down with the ASAP in tow. If a fall or rapid force is experienced, the ASAP reacts (like a seat-belt mechanism) by grabbing the rope to stop uncontrolled descent. Certification: CE EN 353 2. For 10.5- to 13-mm semi-static ropes (EN 1891 type A) certified with the device. Comes with the OK TRIACT automatic-locking carabiner. Weight: 350 g + carabiner (77 g) = 427 g.
