Self-retracting lifeline

January 1, 2012
The DBI-SALA Nano-Lok Self-Retracting Lifelines can be used in place of lanyards and directly attached to any harness, reducing fall clearances. The automatic activating arrester locks quickly to stop falls within inches. At only 1.6 pounds, these lifelines are virtually unnoticeable to the user when worn and provide flexibility. They can protect workers weighing up to 420 pounds.
