NATE, the tower association, has passed along a warning from 3M, a major manufacturer of safety equipment for the tower industry.
Select runs of the company’s DBI-SALA Nano-Lok self-retracting lifeline with anchor hook are under suspicion. First clue, they were manufactured between Sept. 1, 2020 and Aug. 31, 2021, part/model numbers: 3101218, 3101219, 3101241, 3101198, 3101223, 3101224 and 3101249.
The concern is an improperly formed rivet for the top swivel eye that could work loose and fail. 3M has provided instructions on how to inspect the device. If the rivet is formed correctly and secure the unit is safe and can be used.
No accidents have yet been reported.
