Operates quickly and efficiently in the toughest environments

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 Sealed-Blok™ SRL is IP-69K rated to protect against ingress of dust, high temperature, 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™ SRL is essential; it operates quickly and efficiently in the toughest environments. It is one of the most critical parts of a rescue system as it provides the means to retrieve an incapacitated worker to safety.

The Sealed-Blok™ SRL 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 SRLs internal centrifugal energy absorption system will activate, stopping the fall and reducing the forces imposed on the user to safe levels.
