Slingmax® Twin-Path® high-performance slings helped to complete the One World Trade Center Freedom Tower by cradling the spire while it was carefully lifted to its place at the peak of the building. The addition of the 408-foot silver spire brought Freedom Tower to its full height, a symbolic 1,776 feet, making it the tallest building in the Western Hemisphere.
The slings are made of a blend of high-performance fibers, including a high percentage of Dyneema® from DSM Dyneema LLC. Slingmax products are available from ASC Industries Ltd. SLINGMAX® is an association of independently owned and operated rigging products manufacturers.
