The Sealed-Blok range is the solution of choice when the work environment presents contamination risks for fall protection equipment. The galvanized steel cable offers high mechanical strength and good corrosion resistance in standard wet environments. The hook facilitates connection to the dorsal D-ring.
Designed for work at height in harsh conditions. The sealed housing extends equipment service life by protecting the retraction mechanism from abrasive particles and moisture.
The cable is made of galvanized steel, a zinc-treated metal material resistant to corrosion. Unlike textile webbing, a steel cable offers superior resistance to friction and sharp edges. Galvanization ensures extended longevity in environments exposed to moisture.
The anchor must always be above the dorsal D-ring. Max 30-degree angle. Consult the manufacturer's manual for specific stopping distances.


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.
