3M DBI-SALA Ultra-Lok RSQ Self-Retracting Lifeline with Rescue

SKU: DS-350455 Categories: ,


A speed sensing brake stops the fall just like in fall arrest mode

The Ultra-Lok RSQ Self Retracting Lifeline’s exclusive dual-mode operation allows the user, prior to connection, to choose between fall arrest requiring assisted rescue, or self-rescue. After setting the device mode, should a fall occur, the following will happen: Fall Arrest Mode (Assisted Rescue): A speed sensing brake stops the fall, reduces forces imposed on the user to safe levels of 900 lbs. or less and allows for assisted rescue to take place.

  • Exclusive design provides both fall arrest with assisted rescue capabilities and automatic self-rescue for ultimate versatility.
  • Fall arrest mode stops falls within inches and limits the forces to 9 lbs. or less for added safety. Assisted rescue procedures can then be implemented either at the mode selector or remotely with a First-Man-Up pole.
  • Self-rescue mode automatically lowers the user to the next level after a fall.
  • The durable reinforced plastic housing is lightweight and long-lasting and incorporates a built-in carrying handle for easy transportation.
  • 5 ft. (15 m) lifeline extends and retracts automatically enabling the user to move around the work area protected.
  • i-Safe Intelligent Safety System is built into every unit to track inspections, control inventory, and mage information.
