Petzl ASAP Lock Fall Arrester

The Petzl ASAP Lock is a mobile fall arrester that rides a separate backup rope and locks if you fall. Its locking function lets you fix it in place on the rope, which is useful when you are working near the edge or want to limit how far it can travel.

How the ASAP Lock works

The ASAP Lock runs on a separate backup line and slides freely as you move. If you fall or lose control, it grabs the rope and stops you. The lock function lets you hold it at a fixed point on the rope so it will not slide down past you, which is handy when you are setting up near an edge or working from a structure.

In fall-arrest use it is paired with a Petzl energy absorber, such as the ASAP'SORBER, between the device and your harness. Read the instructions for the exact connector and absorber combinations it is approved with. More options are in our fall protection section.

In tree work the ASAP Lock tends to show up in situations that borrow from rope access, such as working from structures, towers or cranes, or where a site rule calls for a separate backup line. For ordinary canopy climbing, most arborists rely on their primary climbing system and training rather than a mobile fall arrester.

Rope, inspection and training

Use it only on the rope types and diameters Petzl lists for it, and check the device locks correctly on your rope before every use. Inspect the cam, body and connector for wear, cracks and debris.

This is life-support equipment. It must be used per the manufacturer's instructions and the applicable standard, including ANSI Z133 for tree work, and only by people trained in rope access and rescue.
