The Simpson Strong-Tie SHH steel header hanger is used to support traditional CFS box headers that are fabricated with top and bottom tracks, as well as large-flange lay-in headers that are common in curtain-wall construction. The connector geometry minimizes drywall buildup, and the screw count has been minimized through extensive testing. A wide array of value-engineered hole patterns are available that will accommodate different load levels while minimizing installed cost.
