The Simpson MIT411.88 MIT Galvanized Top-Flange Joist Hanger for 3-1/2 in. x 11-7/8 in. Engineered Wood by Simpson is purpose-built to support 90 deg. connections of I-joists to headers, delivering maximum down loads while requiring a minimum number of fasteners. Designed for installation before the joist is placed, this top-flange hanger features a Funnel Flange design that simplifies member placement on the job site. Its positive-angle nailing (PAN) system is specifically engineered for I-joists, reducing the risk of flange splitting and speeding up the fastening process - making it a reliable, cost-effective alternative to welded hangers in standard structural framing applications.

Key Features

• Positive-angle nailing (PAN) with intact nail hole material - nails are driven at a more favorable angle to minimize I-joist flange splitting, and because the nail hole material is not removed, the structural integrity of the hanger is fully preserved.
• Optional triangle nail holes for increased uplift capacity - gives installers the flexibility to add uplift resistance where needed, provided properly-secured web stiffeners are used, expanding the hanger's range of structural applications.
• Optional fastening with PAT for steel headers - accommodates steel header applications without requiring a separate connector, reducing the number of components needed on mixed-material framing projects.
• Funnel Flange design - guides I-joists into position more easily before fastening, saving time during installation and reducing the chance of misalignment.
• 16-gauge steel construction - provides the structural strength needed for engineered wood framing connections sized 3-1/2 in. x 11-7/8 in. without adding unnecessary bulk.
• Zinc Galvanized, G90 coating - delivers enhanced corrosion resistance, making this hanger suitable for use in environments where moisture exposure is a concern.
• Cost-effective alternative to welded hangers - provides a proven, code-friendly solution for standard 90 deg. joist-to-header connections at a lower cost than custom-welded options.

Why This Product

• Engineered specifically for I-joist framing - the PAN system and Funnel Flange design work together to address the specific handling and fastening challenges of engineered wood members, reducing splitting risk and simplifying placement compared to connectors designed for dimensional lumber.
• Fewer fasteners, full load performance - the MIT411.88 is designed to achieve maximum down load capacity with a minimum number of fasteners, helping crews work faster without sacrificing structural performance.
• Built-in flexibility for demanding applications - optional triangle nail holes for added uplift capacity and optional PAT fastening for steel headers mean this single hanger can handle a wider range of connection scenarios, reducing the need to source multiple connector types.
• G90 galvanized protection on a domestic-made connector - the Zinc Galvanized, G90 finish provides a meaningful level of corrosion resistance for a long service life, and the hanger is made in the United States to consistent manufacturing standards.
