Before using this equipment, record the product identification information from the ID label in the ‘Inspection and
Maintenance Log’ at the back of this manual.
DESCRIPTION:
Figure 2 identifies key components of the DBI-SALA Sealed-Blok Self-Retracting Devices (SRDs). Sealed-Blok SRDs are drum
wound Wire Rope Lifelines (A) which retract into a sealed 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 Sealed-Blok SRD models covered by this instruction manual. The following SRD Types are available:
• Self-Retracting Lanyard (Figure 2A):
Self-Retracting Lanyards (SRLs) 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 Lanyard with Rescue (Figure 2B):
Self-Retracting Lanyards with Rescue include an integral means for
assisted rescue by raising or lowering the rescue subject. RSRLs are equipped with a 3-Way Emergency Retrieval Hand
Crank (F). Some models include a Tripod Mounting Bracket (G) to mount the SRL on the leg of a Tripod for Confined Space
applications.
