Fast-acting fall arrester limits injury yet allows freedom of movement. Will function in any orientation, and may be mounted overhead.

  • 20 ft. (6.1m) stainless-steel line resists corrosion and abrasion
  • Automatically pays out and retracts into the housing
  • Rugged all-steel construction is sealed against environmental contamination, increasing reliability
  • Three continuously moving, independent locking pawls will engage—even in freezing and icy conditions
  • With a 4.5 foot-per-second locking speed, normal worker movement progresses smoothly
  • Unit will lock up and arrest a fall within 24 in. (61cm)
  • Built-in shock absorber limits fall arrest forces to under 900 lb. (408kg)
  • Corrosion-resistant, self-closing, self-locking steel snap hook on a swivel mount reduces line twisting
  • Load indicator on the snap hook deploys on impact

No factory recertification is required unless unit is involved in a fall.
