The Simpson SHH3/68-KT24 Steel Header Hanger from Simpson is engineered to support traditional cold-formed steel (CFS) box headers fabricated with top and bottom tracks, as well as large-flange lay-in headers common in curtain-wall construction. Built from 68-mil, 14-gauge steel with a G90 zinc galvanized finish, this connector delivers reliable structural performance in CFS framing applications while its value-engineered hole pattern and minimized screw count help reduce installed cost without sacrificing load capacity. Each kit includes 12 right-handed connectors and 12 left-handed connectors, giving installers a matched pair set ready for field use.

Key Features

• Bottom tabs transfer wind load from the horizontal window header to the jamb studs - actively manages lateral forces at the opening while also supporting the header assembly during installation, reducing the need for temporary bracing.
• Tabulated loads based on component assembly testing - gives engineers and inspectors confidence in the published load values and helps mitigate design risk on code-sensitive projects.
• Coped gusset avoids 1 1/2 in. (max.) track legs - allows drywall to be installed flush without modification or additional buildup, saving time on interior finish work.
• 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, maximizing connection efficiency across a wide range of CFS framing configurations.
• 14-gauge, 68-mil steel construction sized for 3-5/8 in. or 4-in.-deep (max.) box headers and large-flange lay-in headers - provides the structural thickness required for demanding curtain-wall and CFS header framing applications.
• G90 zinc galvanized finish - delivers enhanced corrosion resistance suited to the exposed conditions common in commercial and light-gauge steel construction.
• Packaged as 12 right-handed and 12 left-handed connectors - provides a balanced, job-ready assortment so both sides of each header opening are covered without placing separate orders.

Why This Product

• Designed specifically for CFS framing systems - the connector geometry and hole patterns are purpose-built for cold-formed steel box headers and large-flange lay-in headers, making it a precise fit for curtain-wall and light-gauge header rough-in rather than a generic adapter.
• Reduces labor and material costs through smart engineering - the minimized screw count achieved through extensive testing and the coped gusset design that eliminates drywall buildup together help keep both fastener costs and finish-trade labor hours down on commercial CFS projects.
• Broad flange compatibility simplifies procurement - a single connector accommodates five jamb stud flange sizes (1-5/8 in. through 3-1/2 in.), meaning fewer SKUs to manage on site while still achieving even load distribution and minimum eccentricity at the connection.
• Assembly-tested loads backed by Simpson engineering - tabulated values derived from component assembly testing give design professionals a reliable basis for specification, helping to reduce submittal risk and streamline project approvals.

Frequently Asked Questions

What type of headers is the SHH3/68-KT24 designed to support?

The SHH3/68-KT24 is designed to support traditional cold-formed steel (CFS) box headers fabricated with top and bottom tracks, as well as large-flange lay-in headers that are common in curtain-wall construction. It is intended for use with 3-5/8 in. or 4-in.-deep (max.) box headers.

What fasteners are required to install the SHH3/68-KT24 header hanger?

The SHH3/68-KT24 should be installed with #10 screws. The screw-hole layout at the jamb studs accommodates flange sizes of 1-5/8 in., 2 in., 2-1/2 in., 3 in., and 3-1/2 in., allowing load to be evenly distributed along two lines of fasteners.

How does the SHH3/68-KT24 accommodate drywall installation?

The gusset portion of the SHH is coped to avoid 1-1/2 in. (max.) track legs, enabling easier drywall installation without requiring additional buildup or modifications to the surrounding assembly.

What corrosion protection does the SHH3/68-KT24 have, and how many pieces come in a pack?

The SHH3/68-KT24 features a G90 zinc galvanized coating for extra corrosion resistance. Each kit (KT24) includes 24 connectors total - packaged as a box of 12 right-handed connectors and 12 left-handed connectors - providing both orientations needed for a complete header installation.
