DBI-Sala 3400171 Sealed-Blok Self-Retracting Lifeline Fall Arrest SRL

The DBI-Sala Sealed-Blok Self-Retracting Lifeline (SRL) is a professional-grade fall protection device engineered for workers operating at height in demanding industrial, construction, and maintenance environments. Designed with a sealed housing to resist dust, moisture, and contaminants, the Sealed-Blok delivers reliable performance where standard SRLs may fail.

Key Features:

• Sealed housing protects internal components from dirt, moisture, and harsh environmental conditions
• Self-retracting lifeline automatically extends and retracts, keeping slack minimized and reducing trip hazards
• Fast-acting brake system engages instantly upon freefall detection, limiting fall distance and arrest forces
• Swivel snap hook allows 360-degree connection flexibility, reducing lifeline twist during movement
• Durable construction built to meet ANSI/ASSE Z359.14 and OSHA standards for self-retracting devices
• Compact and lightweight design for easy portability and overhead anchorage attachment
• Compatible with standard anchorage connectors and dorsal D-ring harness attachment points

The DBI-Sala Sealed-Blok SRL is a trusted fall arrest solution from 3M's DBI-Sala brand — one of the most recognized names in personal fall protection. It is ideal for use in environments where exposure to the elements could compromise the integrity of unsealed equipment, making it the preferred choice for oil and gas, petrochemical, utilities, and heavy construction applications.
