The Simpson MIU1.56/11 Face-Mount I-Joist Hanger (1 1/2 x 11 7/8) from Simpson is an engineered face-mount connector built for commercial, high-load, and double I-joist applications where reliable structural performance is critical. Designed to seat and secure I-joists without requiring web stiffeners in standard configurations, this hanger simplifies framing workflows while supporting the demanding load requirements of professional construction projects.

Key Features

• Commercial and high-load I-joist compatibility - purpose-built for double I-joist and heavy-load applications, giving contractors a single connector that handles demanding structural scenarios without compromise.
• No web stiffeners required in standard use - eliminates an extra installation step in typical configurations, reducing material costs and speeding up the framing process on the job site.
• Positive-angle nailing (PAN) - minimizes splitting of the I-joist flanges during fastening and allows nailing from a more accessible angle, improving accuracy and reducing installation time.
• Speed prongs for temporary positioning - hold the connector in place hands-free during initial placement, making one-person installation faster and more manageable.
• Optional triangle joist nail holes - allow four additional 10dx1 1/2 in. joist nails to be added for increased uplift capacity when project conditions require it (note: web stiffeners are required when using this option).
• Zinc Galvanized G90 coating - provides corrosion resistance suited to the environments where structural framing connectors are regularly exposed to moisture during and after construction.

Why This Product

• Engineered for professional-grade load demands - designed specifically for commercial, high-load, and double I-joist applications, this hanger addresses the structural requirements that standard hangers are not rated to handle.
• Installation-friendly design saves time on site - the combination of speed prongs for hands-free positioning and positive-angle nailing means faster, more accurate installation with fewer adjustments, reducing labor time per connector.
• Flexible uplift capacity for variable project requirements - the optional triangle joist nail hole design allows the hanger to achieve a total uplift load of 975 lbs. when needed, giving builders adaptability across different structural conditions without switching to a different product.
• Trusted Simpson quality with domestic production - built to Simpson engineering standards and produced in the United States, this connector delivers the consistency and reliability that structural framing professionals depend on.

Frequently Asked Questions

Does the MIU1.56/11 require web stiffeners for standard installations?

The MIU hanger is designed for commercial, high-load and double I-joist applications without requiring web stiffeners in standard use. However, properly attached web stiffeners are required when utilizing the optional triangle joist nail holes for additional uplift.

What is the maximum uplift load achievable with the MIU1.56/11?

By adding four additional 10dx1-1/2 in. joist nails to the optional triangle joist nail holes, the MIU achieves a total uplift load of 975 lbs.

What does the positive-angle nailing (PAN) feature do?

Positive-angle nailing (PAN) minimizes splitting of the I-joist flanges during installation while also permitting nailing from a better angle, saving time and improving accuracy on the job site.

What coating does the MIU1.56/11 have, and what fasteners should be used?

The MIU1.56/11 features a Zinc Galvanized G90 coating for corrosion resistance. Always use all specified fasteners during installation, and verify that the header can accommodate the required fasteners specified in the load table before proceeding.
