IP-69K rated for the most challenging job sites

Using a revolutionary patented design, the 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline (SRL) helps isolate parts, such as the motor spring and brake, from impurities like grease, moisture, dirt, and other debris. Developed for harsh working environments, the Sealed-Blok™ SRL is IP-69K rated to protect against dust ingress, high temperatures, and high-pressure water. These lifelines are available in configurations for Overhead, Retrieval, and RSQ/Rescue SRL.

The 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline (SRL) is essential for confined space and entry rescue as it operates quickly and efficiently in even the most challenging conditions. It is one of the most critical parts of a rescue system as it provides the means to safely retrieve an incapacitated worker. The lifeline is designed to extend as the user moves away and retract automatically, allowing the user to move around at normal speeds within a recommended working area. In the event of a fall, the SRL's internal centrifugal energy absorption system will activate, preventing the fall and reducing the forces imposed on the user to safe levels.
