DESCRIPTION:

Figure 2 identifies key components of the DBI-SALA® Ultra-Lok™ Self-Retracting Devices (SRDs). Ultra-Lok 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 Ultra-Lok SRD models covered by this instruction manual. The following SRD Types are available:

•  Self-Retracting Device (1):

 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 Rescue (2):

 Self-Retracting Devices with Rescue include an integral means for assisted 

rescue by raising or lowering the rescue subject. RSRDs are equipped with a 3-Way Emergency Retrieval Hand Crank 

(F). Some models include a Tripod Mounting Bracket (G) to mount the SRD on the leg of a Tripod for Confined Space 

applications.
