The Simpson HH4 HH Galvanized Header Hanger from Simpson Strong-Tie is built for fast, accurate installation of door and window headers and other cross members in wood-framed construction. By supporting the header from above, this connector eliminates the need for studs below the header, streamlining the framing process and reinforcing the structure against downward load forces. Made from 16-gauge steel with a G90 Zinc Galvanized coating, the HH4 is a dependable solution for contractors and framers looking to work more efficiently without sacrificing structural performance.

Key Features

• Protects header installations from downward forces - engineered to carry load transfer away from the header connection, keeping door and window openings structurally sound
• Eliminates the need for studs below the header - fewer framing members means less material, less labor, and a cleaner rough opening
• Fast, easy alternative to traditional framing methods - speeds up the job by removing extra layout and nailing steps associated with conventional trimmer stud framing
• Sized for nominal 4x members - fits the header securely with a seat width of 3-1/2 in. and a seat height of 2-13/16 in., so there is no guesswork on compatibility
• 16-gauge steel construction - provides the strength and rigidity needed to perform reliably in structural framing applications
• G90 Zinc Galvanized finish - delivers extra corrosion resistance, making the hanger suitable for a wide range of framing environments where moisture exposure is a concern

Why This Product

• Simplifies rough openings without compromising strength - by replacing the traditional trimmer stud assembly, the HH4 reduces the number of framing components required while still protecting the header from download forces
• Built for job-site efficiency - Simpson Strong-Tie engineered this header hanger specifically to speed up installation of door and window headers, cutting down on framing time and keeping projects on schedule
• Corrosion-resistant from the start - the G90 Zinc Galvanized coating goes beyond basic protection, making the HH4 a reliable long-term connector in conditions where bare steel would deteriorate
• Consistent, code-compatible fastening - designed to install with standard nail sizes including 10d x 1 1/2 in. and 16d common nails, so fastener compatibility is straightforward on any framing crew
