The 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline (SRL) incorporates a patented concept that helps separate components, such as the motor spring and brake, from foreign elements such as grease, moisture, and dirt. The 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline is IP-69K rated to provide protection against ingress of dust, high tempeatures, and high pressure water, for use in extreme environmental conditions. These lifelines are available in Overhead, Retrieval, and RSQ / Rescue SRL configurations.

When it comes to confined space and entry rescue, the 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline (SRL) is essential; it operates quickly and efficiently in the toughest environments. The 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline is one of the most critical parts of a rescue system as it provides the means to retrieve an incapacitated worker to safety. The SRL’s lifeline is designed to extend as the user moves away and retracts automatically, enabling the user to move around within a recommended working area at normal speeds. Should a fall occur, the SRL’s internal centrifugal energy absorption system will activate, stopping the fall and reducing the forces imposed on the user to safe levels.
