Twin Leg Manyard II Stretchable Lanyard
The twin Manyard keeps a hook on the structure through every move: two stretchable absorbing legs share one SofStop-style core at the harness end, and both legs contract when slack so the parked leg does not dangle into trouble. Rebar hooks at both anchor ends close over bar and angle directly.
Certified to ANSI Z359.13 and compliant with OSHA 1926.502 and 1910.140, rated for a 310 lb worker with 5,000 lb steel hardware. Twin legs keep 100 percent tie-off through every transfer.
Who Needs This Product
The twin-leg version keeps a hook on the structure through every move, satisfying 100 percent tie-off policies without a second lanyard flopping loose. Like every energy absorbing lanyard, it trades clearance for economy: generous overhead anchors are its home field, and the TurboLite+ PFL takes over when heights get tight.
Features
100 Percent Tie-Off
Connect the second leg before releasing the first when transferring; there is never a moment without a connection.
Both Legs Contract
The stretchable design pulls each slack leg short, so the parked leg rides on the harness instead of dragging.
Energy Absorber
The absorber core expands under load, limiting average arrest force to 900 lb and capping deceleration at 3.5 ft per ANSI Z359.13.
Warning Flag
A visual indicator shows if the lanyard has been loaded in a fall, flagging it for immediate retirement.
Locking Hooks
Double-action locking hooks at both ends cannot open accidentally against a D-ring or anchor.
Steel Hardware
Hooks rated to 5,000 lb tensile keep the connections stronger than the standard requires.

Mind the clearance. A 6 ft energy absorbing lanyard needs roughly 17 to 18 ft of clearance below the anchor after free fall, deceleration, harness stretch, and safety margin. Run your numbers with our fall protection calculator before the first connection.
