Smart Lock distinguishes normal movements from a fall. Stainless cable does not rust and resists aggressive environments. Always calculate minimum clearance before use.
Glass-filled nylon housing. IRF (RFID) technology.
The cable is made of stainless steel, a corrosion-resistant metal alloy requiring no zinc coating. Stainless steel is preferred in aggressive environments: marine, offshore, saltwater, food processing, pharmaceutical.
About the anchor point:
The anchor must always be above the dorsal D-ring, positioned vertically. Max 30-degree angle. Consult the manufacturer's manual for specific stopping distances.

The Smart Lock motion-capture mechanism distinguishes normal work movements from an actual fall: it reduces nuisance lock-ups while ensuring an immediate arrest in the event of a fall. Its 420 lb (190 kg) load capacity includes the worker, clothing, tools and equipment, making it ideal for heavy industrial work on scaffolds, mezzanines and platforms.
The stainless steel cable offers maximum corrosion resistance, ideal for marine, chemical or food-processing environments where galvanized steel is not enough. The glass-filled nylon housing stays light yet rugged, and the built-in IRF (RFID) technology streamlines inventory management and inspection traceability.
Perform a routine inspection before each use. A qualified person must inspect every 90 or 180 days. Recommended service life: 5 years. Sylprotec inspection service available.
Any equipment subjected to a fall or impact must be taken out of service.
Clean with mild soap and warm water (37°C). No bleach. Air dry.
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.
La version inoxydable 50 pi est recommandée pour les grandes structures en milieux corrosifs : offshore, marins, eau salée, industries pharmaceutiques. L'inox ne rouille pas et résiste aux agents chimiques agressifs. La longueur de 50 pi est idéale pour les structures très étendues.
