July 25, 2019 Recall Notice Details

3M has determined that in a fall and under certain conditions, the energy absorber of these devices may not properly deploy.

3M’s Twin-Leg Nano-Loks are used as part of a personal fall protection system that connects two self-retracting lifelines/devices (SRLs/SRDs) directly under the dorsal D-ring of a worker’s harness.

The Twin-Leg Nano-Lok edge is intended to be anchored at foot-level, is designed for sharp and/or leading-edge applications and incorporates an energy absorber. The Twin-Leg Nano-Lok Wrap Back is intended for wrapping around an anchor and incorporates a similar energy absorber.

There have been no reports of accidents or injuries associated with this issue, however, in a fall failure to deploy could expose the worker to serious injury or death.

In the interests of worker safety, 3M launched this global stop use /recall; these products must be removed from service immediately.

Per the original July 25th notice issued by 3M, these devices will be repaired or replaced as soon as a solution is identified, tested and certified. Alternatively, end-users may elect to receive cash for their returned devices.

August 6, 2019 Recall Update Details

Per their August 6, 2019 Recall Update Notice: A robust solution has been identified, tested and certified to the ANSI standard Z359.14. With this solution, the energy absorber of these units will deploy properly under all circumstances of use for which these products are intended. The affected units can now be repaired and safely returned to service.

Due to regional regulatory requirements, this solution is currently available ONLY in regions that recognize the ANSI standard. As other regulatory certifications are received, this solution will be made available in those regions. Until your unit has been repaired or replaced as described above, the “Stop Use and Recall” remains in effect and these units must be removed from service.

Note: At the time of this update, the solution described above does not include the Twin-Leg Nano-Lok™ Wrap Back SRL or the Twin-Leg Nano-Lok™ edge Tie Back versions.

Users/Owners: Please go to and follow the instructions on how to return your device. Note that cash is no longer an option for owners/users of ANSI versions of the affected units for which a solution is available. The cash option remains available until a solution has been certified for the remaining SKUs (see website for a complete list of SKUs that can be repaired at this time).
