The Dusky is a compact self-retracting steel cable lifeline (SRL) that can be used vertically with a maximum deviation of 40 degrees. With a 3m maximum working length, the Dusky connects directly to harness via a swivel anchorage eye to prevent the webbing twisting.
Its self-locking system ensures it’s ready to engage in the event of a fall and the webbing is kept under constant tension to reduce the fall distance.
