PRODUCT OVERVIEW:
Figure 1 illustrates the product models covered by this instruction. Self-Retracting Devices (SRDs) are drum-wound lifelines that
retract into solid housings.
The following SRD types are covered by this instruction:
• Self-Retracting Device (Figures 1.1, 1.2; 2.1, 2.2): Self-Retracting Devices (SRDs) are suitable for applications where
the lifeline remains generally vertical during use. This type may be used for Fall Arrest or Restraint applications.
Figure 2 identifies key components of the available SRD models. In a standard SRD, the Lifeline (A) extends and retracts from
within the Housing (B). The Top Connector (D) secures the SRD to its mounting point and is connected to the SRD by means
of the Swivel Eye (E). The Bottom Connector (C) is secured at the end of the Lifeline. Depending on system configuration, the
Bottom Connector will attach to either the designated attachment element of the user’s full body harness or to the system’s
anchorage point. Energy Absorbers (F) dissipate kinetic energy and limit deceleration forces during fall arrest.
SRD models are available in single-SRD and twin-SRD configurations. Twin-SRD models include a single Top Connector (D) to be
shared between the two SRDs. These connectors are designed to interface with harnesses so that the Twin-SRD model may be
worn on the user’s back. Twin-SRD models may be used to maintain 100-percent tie-off when transferring between anchorage
points.
Each product model has its own particular size and its own combination of components as listed in Figure 1. See Table 1 for
more information on Component Specifications.
Certain SRD models in this instruction may be used in environments with additional hazards. See Figure 1 for identification of
these models.
• Arc Flash: “Arc Flash” models meet the requirements of ASTM F887 and are designed for use in environments where an
arc flash or electrical explosion could occur.
