The Simpson MIT4.28/9.5 Top-Flange Joist Hanger for 4-1/8 in. x 9-1/2 in. Engineered Wood from Simpson is engineered to support 90 deg. connections of I-joists to headers, delivering maximum down loads while requiring a minimum number of fasteners. Designed to be installed before the joist is in place, this top-flange hanger features a Funnel Flange design for easier member placement, making it a reliable and efficient choice for engineered wood framing projects where precision and structural performance matter.

Key Features

• Positive-angle nailing (PAN) specifically created for I-joists - minimizes splitting of the flanges while permitting time-saving nailing from a better angle, keeping your installation on schedule without compromising structural integrity.
• Nail hole material is not removed with positive-angle nailing - preserves the full strength of the connection point, so the joist-to-header joint maintains its load-carrying capacity.
• Optional triangle nail holes for increased uplift capacity - gives you a straightforward path to a stronger connection when uplift resistance is a project requirement; optional uplift nailing requires the addition of properly-secured web stiffeners.
• Cost-effective solution for standard 90 deg. connections - provides the structural performance of a rigid connection at a lower cost compared to welded hangers, helping keep project budgets in check.
• Optional fastening with PAT for steel applications/header - adds versatility for projects where a steel header is used, so one hanger can adapt to different framing scenarios.
• 16-gauge steel construction - delivers the rigidity and load capacity needed for engineered wood framing without adding unnecessary bulk to the connection.
• Zinc Galvanized G90 finish - provides extra corrosion resistance, extending the service life of the connector in moisture-prone framing environments.

Why This Product

• Built around engineered wood framing demands - the Funnel Flange design and positive-angle nailing (PAN) technology are both specifically engineered for I-joist applications, reducing the risk of flange splitting that standard hangers can cause during installation.
• Installs before the joist goes in - the top-flange design allows the hanger to be set on the header first, simplifying placement and reducing the need for repositioning or additional labor during the framing process.
• Flexible enough for steel and wood headers - with optional PAT fastening for steel headers alongside standard wood-header nailing, this hanger covers a wider range of structural connection scenarios without requiring a separate product.
• Corrosion-resistant finish for long-term reliability - the G90 zinc galvanized coating means the connector holds up in demanding conditions, protecting the structural connection over the life of the building.
