Nano-Lok Self-Retracting Lifeline Tie-Backs (SRLs). Nano-Lok SRLs
are 9 ft. (2.7 m) or 11 ft (3.3 m) Lanyards, equipped with an in-line Load Indicator (C) and RFID tag (D). The lifeline (E)
retracts into a Thermoplastic Housing (F) . A Swivel Eye (G) on the top of the Housing allows attachment to a valid anchorage
connection point with a Carabiner, or mounting on a Full Body Harness with a Harness Interface. They are available in multiple
model configurations that allow tie-back (B) attachment to an anchorage point with a snap hook (A) and single or dual mounting
on a Full Body Harness (see Figure 7). The Nano-Lok SRL automatically locks at the onset of a fall to arrest the fall, but pays out
and retracts lifeline during normal movement by the attached user. The Tie-Back hook and Tie-Back portion of lifeline allow this
unit to be tied back around structural members that meet anchorage requirements. See Table 1 for Nano-Lok SRL and connector
specifications.
Hot Work: Fire resistant “Hot Work” models are available for welding, foundry work, etc., where the SRL may be exposed
to sparks or flames.
Arc Flash : Meets the test requirements of the ASTM F887 standard and is designed for use in environments where an arc
flash (electrical explosion) could occur.
