The combination of Smart Lock and stainless steel cable makes the FPLR3503823 the most robust solution in the range for extreme environments. The intelligent locking system ensures workers are not hindered by nuisance lock-ups even during sudden movements on metal structures exposed to weather or saltwater. RFID traceability enables rigorous management of mandatory inspections.
Smart Lock uses a motion-sensing mechanism to distinguish normal work movements from an actual fall. It reduces nuisance lock-ups while ensuring immediate arrest. 420 lb capacity for workers with heavy equipment.
