Maintenance Log' at the back of this manual.
DESCRIPTION:
Figure 2 identifies key components of the Protecta Rebel Self-Retracting Devices (SRDs). Rebel SRDs are drum wound Wire
Rope Lifelines (A) which retract into a thermoplastic or aluminum Housing (B). They can hang from anchorage by a Carabiner
attached through the Swivel Eye (C) on the top of the SRD. A Self-Locking Snap Hook (D) on the end of the Lifeline attaches to
the designated Fall Arrest connection on a Full Body Harness. A Bumper (E), protects the Wire Rope and Ferrules securing the
Snap Hook from abrasion and corrosion.
Figure 1 defines the Rebel SRD models covered by this instruction manual. The following SRD Types are available:
• Self-Retracting Device (Figure 2A): Self-Retracting Devices (SRDs) are suitable for applications where the lifeline
remains generally vertical during use and possible Free Fall is limited to 2 ft (0.6 m).
• Self-Retracting Device with Leading Edge (Figure 2B): Self-Retracting Lanyards with Leading Edge (SRD-LEs) are
suitable for applications where the lifeline remains generally horizontally during use and possible Free Fall is limited to 5 ft
(1.5 m). SRD-LEs have an integral Energy Absorber (F), or similar component, to withstand impact loading of the lifeline
over a sharp or abrasive edge during fall arrest and minimize fall arrest forces on the user.
• Self-Retracting Device with Rescue (Figure 2C): Self-Retracting Lanyards with Rescue (SRD-Rs) include an integral
means for assisted rescue by raising or lowering the rescue subject. SRD-Rs are equipped with a 3-Way Emergency
Retrieval Hand Crank (G). Some models include a Tripod Mounting Bracket (H) to mount the SRD-R on the leg of a Tripod
for Confined Space applications.
