10193560 V-Series Tieback Single-Leg Energy Absorbing 6′ Tie-Back Lanyard

The V-SERIES Tie-back safety lanyard uses an FP5K Carabiner
which can be tied directly back to the lanyard. This product
is designed to keep fall arrest forces below 900 pounds. Its
unique carabiner body shape helps avoid confusion with
standard connectors not designed for tie-back applications.
