3M™ DBI-SALA® Nano-Lok™ Edge 3500232 Twin-Leg Self-Retracting Lifeline 

Class 2 Leading Edge Safety. 100% Continuous Tie-Off. Zero-Downtime Quick Connect.

The 3M DBI-SALA Nano-Lok Edge Twin-Leg Self-Retracting Lifeline (3500232) introduces uncompromising leading-edge protection, continuous connection safety, and lightweight ergonomic wear directly to high-risk industrial environments. Purpose-built to conquer the extreme mechanical shearing hazards of foot-level tie-offs and sharp concrete or steel roof boundaries, this ANSI Class 2 certified twin-leg SRL eliminates the weight and tripping hazards of traditional shock-absorbing rope lanyards. It provides structural steel ironworkers, commercial roofing contractors, scaffolding crews, and industrial facility technicians with a highly responsive mechanical arrest barrier optimized to stop a fall within inches safely.

Rugged architectural durability and streamlined user mobility serve as the backbone of this elite Nano-Lok Edge Personal SRL configuration. The system is engineered with dual 8 ft (2.4m) lines of 3/16" (5mm) galvanized steel aircraft-wire cable, providing superior field abrasion and cut resistance against ragged edges. Its innovative direct-to-harness quick-connect pin assembly secures directly into standard webbing trails just below the dorsal D-ring, keeping your harness back open for rescue equipment while eliminating uncomfortable back flopping or line dragging. Complete with an integrated backpack-style external energy absorber and a responsive, speed-sensing automatic brake system, this compact system allows crews to execute 100% "leap-frog" transitions between anchors without fear of constant tool lockups.

Why the 3M DBI-SALA Nano-Lok Edge 3500232 Anchors Your Team:

• ANSI Class 2 Leading Edge Rated: Rigorously tested and certified for foot-level tie-offs and sharp, abrasive edge exposures common in construction.
• Twin-Leg 100% Continuous Tie-Off: Allows workers to move dynamically between structural anchor points without ever being unprotected.
• Webbing-Level Quick Connect: Direct attachment pin docks cleanly behind the shoulder blades, freeing up the main dorsal D-ring for external retrieval lines.
• Galvanized Steel Core Cable: Dual 3/16-inch high-tensile wire lifelines resist severe jobsite wear, friction cuts, and kinking much better than standard web straps.
• Speed-Sensing Brake Shield: Advanced reactive internal brakes stop fall momentum within inches, providing critical low-clearance drop protection.
