Recall notice update: 3M™ DBI-SALA® Twin-Leg Nano-Lok™ edge Self-Retracting Lifelines

Stop Use & Recall Notice 
November 14, 2019
3M™ DBI-SALA® Twin-Leg Nano-Lok™ edge  
Self-Retracting Lifelines (CSA Canadian Versions Only)

3M Fall Protection is pleased to announce it has resolved the partial deployment of the energy absorber that led to the immediate stop use and recall of the 3M™ DBI-SALA® Twin-Leg Nano-Lok™ edge SRL issued in July 2019. A robust solution has been identified, tested and certified to the CSA standard Z259.2.2-98. 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, CE & CSA standards. 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. The original Notice and an updated list of affected products by part number and regulatory standard can be found at We also expect to be able to supply new Nano-Lok Twin Edge SRL’s certified to CSA Z259.2.2-17 in the coming weeks.   
Users/Owners: Please go to and follow the instructions on how to return your units(s). We will inspect and repair or replace your unit and return it to you at 3M’s expense. If our inspection determines that your Nano-Lok needs to be taken out of service for reasons unrelated to the stop use/recall, we will inform you of that fact. To minimize any disruption to your business, we will also provide you a list of authorized repair centers near you that can complete the inspection and repair. Note that the cash option is no longer available as of November 19, 2019 for owners/users of CSA versions of the affected units for which a solution is now available.  
Distributors: Please contact our Customer Service department at 1-833-998-2243 or email us at to obtain a listing of all Twin-Leg Nano-Lok edge and Twin-Leg Wrap Back SRLs sold to you. If you have any of these devices in stock, please return them to 3M Fall Protection for replacement at 3M’s expense. Please immediately forward the original Notice together with this Update to any of your customers/users who have purchased Twin-Leg Nano-Lok edge and/or Twin-Leg Nano-Lok Wrap Back SRLs from you and ask them to read and comply with this Notice & Update immediately.
