Trusted. Durable. Reliable

3M™ DBI-SALA® Sealed-Blok™ family of SRL’s have the most comprehensive line of sealed SRL’s in the industry. These Self-retracting Lifelines stand up to the harshest of environments and feature a heavy duty design specifically engineered to resist corrosion. Sealed-Blok™ SRL’s use stainless-steel plug ends and are housed within shiny aluminum for weather-proofing. These SRL’s are also certified for horizontal applications.

The components within these products are guaranteed to last. The “Sealed-Blok” SRL’s are completely sealed, meaning the interior components are completely protected against continuous submersion in water.
