The Simpson MIT3511.88 MIT Galvanized Top-Flange Joist Hanger from Simpson Strong-Tie is engineered to support standard 90 deg. connections of I-joists to headers, delivering maximum down loads while requiring a minimum number of fasteners. Built for use with engineered wood members sized at 2-5/16 in. x 11-7/8 in., this top-flange hanger features a Funnel Flange design that simplifies placement of members before the joist is set, making it a practical choice for engineered wood framing applications where accuracy and efficiency both matter.

Key Features

• Positive-angle nailing (PAN) specifically designed for I-joists - minimizes splitting of the flanges while allowing nailing from a better angle, saving time on the job without sacrificing structural integrity.
• Nail hole material is not removed with PAN - preserves the strength of each connection point, maintaining the structural integrity of the I-joist flange throughout installation.
• Optional triangle nail holes for increased uplift capacity - gives installers flexibility to meet higher uplift demands when paired with properly-secured web stiffeners, adapting the hanger to more demanding load conditions.
• Funnel Flange design - allows the hanger to be installed before the joist is placed, streamlining the framing sequence and reducing positioning errors in the field.
• Cost-effective alternative to welded hangers - provides a reliable standard 90 deg. connection without the added expense or lead time of custom welded solutions.
• Optional fastening with PAT for steel header applications - extends versatility beyond wood-to-wood connections, making this hanger suitable for mixed-material framing scenarios.
• Made from 16-gauge steel with G90 zinc galvanized coating - delivers the structural rigidity and corrosion resistance needed for demanding engineered wood framing environments.

Why This Product

• Built around the specific demands of I-joist framing - the PAN system and Funnel Flange design work together to address the two biggest challenges of I-joist installation: flange splitting and accurate member placement, giving contractors a hanger engineered for the task rather than adapted to it.
• Flexible uplift options without swapping hardware - the optional triangle nail holes allow the same hanger to meet standard or elevated uplift requirements, reducing the need to stock multiple connector types for similar applications.
• Steel and wood header compatibility in one connector - with optional PAT fastening for steel applications, this I-joist hanger works across a broader range of header materials, adding value on mixed-construction projects.
• G90 galvanized protection on a heavy-duty 16-gauge body - the combination of robust gauge and corrosion-resistant finish means this connector is built to hold up in the conditions where engineered lumber framing is most commonly used, without requiring upgrades or substitutions.
