One of the biggest challenges in fall protection is when the anchorage is too high to access and the clearance distance is too small. retractable fall arrester blocks provide an ideal solution for such a problem. can be anchored to a single point and allows the user to move uninhibited at different levels. the connecting lengths is such that is retracts or extends to different lengths as required, is always taut with no slack. in the event of a fall, the block locks immediately with minimum fall, distance & lowers the impact of force to less than 6 kn.
