Maintenance Log’ at the back of this manual.
DESCRIPTION:
Figure 2 identifies key components of the 3M™ DBI-SALA
®
Nano-Lok Self-Retracting Devices (SRDs). Nano-Lok SRDs are drum
wound Web Lifelines (A) with an in-line Energy Absorber (B) that retracts into a Nylon Housing (C). A Swivel Eye (D) on the
top of the Housing allows attachment to a valid anchorage connection point with a Carabiner (E), or mounting on a Full Body
Harness with a Harness Interface (F). Figure 1 identifies available Nano-Lok models and their connector configurations. See
Table 1 for Nano-Lok SRD and connector specifications.
