The Simpson SHH Steel Header Hanger is engineered to support traditional cold-formed steel box headers fabricated with top and bottom tracks, as well as large-flange lay-in headers commonly found in curtain-wall construction. Formed from 54-mil, 16-gauge G90 galvanized steel, this connector keeps installed costs low through a value-engineered hole pattern design, and its geometry is specifically shaped to minimize drywall buildup. Extensive testing has been used to optimize the screw count, making the SHH a reliable, efficient solution for professional CFS framing at jamb and header connections. Each package contains 12 right-handed connectors and 12 left-handed connectors, giving installers a balanced, job-ready supply of both orientations.

Key Features

• Bottom tabs transfer wind load from the horizontal window header to the jamb studs - actively redistributes lateral forces where they belong while also providing physical support to hold the header assembly in position during installation, reducing the need for temporary bracing.
• Tabulated loads are based on component assembly testing - gives engineers and inspectors confidence in the design values, helping to mitigate design risk on the job and simplify plan approval.
• Gusset is coped to avoid 1 1/2 in. (max.) track legs - creates clearance for drywall installation without additional field modification, saving labor time and preserving a clean finished wall profile.
• Screw-hole layout accommodates jamb stud flange sizes of 1-5/8 in., 2 in., 2-1/2 in., 3 in., and 3-1/2 in. - distributes load evenly along two lines of fasteners so each jamb stud carries equal axial load with minimum eccentricity, improving structural performance across a wide range of stud profiles without requiring separate connectors.
• Made from 54-mil, 16-gauge steel for use with 6-in.-deep (min.) box headers - provides the structural thickness required for heavy-duty CFS header applications, ensuring the connector is appropriately sized for the loads it will encounter.
• G90 galvanized coating - delivers extra corrosion resistance that helps protect the connector in demanding construction environments and extends the service life of the assembly.
• Packaged as 12 right-handed and 12 left-handed connectors - supplies both orientations in a single order so crews can move efficiently from one jamb to the other without sourcing additional hardware mid-project.

Why This Product

• Versatile flange compatibility reduces inventory complexity - the multi-flange screw-hole layout works across five common jamb stud flange sizes, meaning one connector model can cover a wide range of CFS framing assemblies on the same project rather than requiring multiple SKUs.
• Testing-backed load values support design and code compliance - because tabulated loads are derived from component assembly testing, designers can apply published values with confidence and reduce the engineering legwork typically associated with specifying connection hardware.
• Geometry engineered to simplify the full installation sequence - the coped gusset minimizes drywall buildup and the bottom tabs hold the header during installation, together addressing two common field pain points in a single connector without add-on accessories.
• Value-engineered hole patterns keep total installed cost in check - the optimized screw count and array of hole patterns mean fewer fasteners are needed to achieve the required load, which translates directly into reduced material and labor costs on large curtain-wall or CFS framing projects.
