Dual Sense Motion Technology

F.L.O.™ is the world’s first Self-Retracting Lifeline to feature dual motion detection—sensing both velocity and acceleration. Unlike traditional devices that react to any quick motion, F.L.O.™ is smart enough to tell the difference between a fall and fast-paced work.

Reduces Nuisance Lock-Ups
Fewer snags. Fewer stops. Less frustration. F.L.O.™ keeps up with how people actually work.

Unlocks Peak Productivity
Less downtime means more done. F.L.O.™ improves crew flow, speed, and focus across the job site.

Reduces Fall Clearance & Arrest Forces
Don’t compromise. F.L.O.™ delivers the lowest fall clearance and arrest force in one premium package.

Boosts Compliance
When equipment works with you, not against you, crews stay tied off and protected—no shortcuts.
