PRODUCT OVERVIEW:

Figure 1 illustrates the 3M™ Protecta
retract into thermoplastic or aluminum housings.
The following SRD types are covered by this instruction:
• Self-Retracting Device (Figures 1.1, 2.1): 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.
• Self-Retracting Device with Leading Edge (Figures 1.2, 2.2): Self-Retracting Devices with Leading Edge (SRD-
LEs) are suitable for applications where the lifeline remains generally horizontal during use. SRD-LEs have an integral
energy absorber to withstand impact loading of the lifeline over a sharp or abrasive edge during fall arrest and
minimize fall arrest forces on the user. This type may be used for Fall Arrest or Restraint applications.
• Self-Retracting Device with Rescue (Figures 1.3, 2.3): Self-Retracting Devices with Rescue (SRD-Rs) include an
integral means for assisted rescue by raising or lowering the rescue subject. This type may be used for Fall Arrest,
Restraint, or Rescue 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) mounted on the SRD secures the SRD to the anchorage 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 and attaches to the
designated Fall Arrest attachment element of the user's full body harness. Energy Absorbers (F) dissipate kinetic energy and
limit deceleration forces during fall arrest.
SRD-R models covered in this instruction include some additional components. The Rotation Handle (G) is used to retrieve the
Lifeline (A) after the Bottom Connector (C) has been secured to the harness of the subject of rescue. The Bracket (H) enables
the SRD-R to be mounted to a tripod during use.
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.
