Petzl ASAP Mobile Fall Arrester B71
London Bridge fell down. So did Humpty Dumpty. However, we don't want you to experience that freefall into oblivion. All the King's men are on unemployment now and won't be jumping on any horses to try and put you back together. Nosiree. Use a Petzl B71 ASAP Mobile Fall Arrester, and you won't have to worry about cracking up or falling down.
When used on a safety rope, the Mobile Fall Arrester does just that: stops a fall, slide or uncontrolled descent. Even if you grab it while falling, it will lock into place. It's designed to work on both vertical and angled ropes, and will move along the rope without manual intervention, both upwards and down. And for all its staying power, it's also easy to install and remove at any point on the rope with a quick adjustment. It comes with the OK TRIACT automatic locking carabiner. For 10.5 to 13 mm semi-static ropes (EN 1891 type A) certified with the device.
All nursery rhyme references aside, the Petzl B71 ASAP Mobile Fall Arrester is one piece of equipment you can't afford to be without on your next climb.
