Description
The 3M™ DBI-SALA® Nano-Lok™ Edge Self-Retracting Lifeline (SRL) models 3500219 and 3500234 are expertly engineered to handle leading edge and foot-level tie-off applications in construction and industrial environments. These lifelines provide unmatched safety with their galvanized cable design, reinforced energy absorbers, and secure steel hooks with locking rebar noses.
Whether using the single-leg configuration of the 3500219 or the twin-leg version of the 3500234 for 100% tie-off scenarios, both units offer rapid-activating braking systems that minimize free-fall distance and reduce force on the body in the event of a fall. The durable thermoplastic housing, direct-to-harness mounting, and lightweight form factor make these SRLs an ideal solution for high-risk elevated tasks.
Key Features
Configuration Options: Available in both single-leg (3500219) and twin-leg (3500234) versions.
Steel Hook with Steel Rebar Locking Nose: High-strength anchor connection designed for secure attachment to large structures.
Fast-Acting Brake Mechanism: Locks quickly to reduce fall distances and minimize injury risk.
Durable Cable Construction: 8 ft galvanized steel cable offers edge resistance in harsh work environments.
Compact, Lightweight Housing: Thermoplastic body stays clear of movement and tools.
Direct Harness Connection: Quick-connect system reduces trip hazards and simplifies donning.
Visual Impact Indicator: Clearly shows when unit has been involved in a fall.
RFID Equipped: Enables digital inspection and inventory tracking.
