Product Description
The Simpson MIU4.12/11 Face-Mount I-Joist Hanger 4x11-7/8 by Simpson is an engineered face-mount connector built for commercial, high-load, and double I-joist framing applications. Designed to accommodate a 4 in. x 11-7/8 in. I-joist, this hanger simplifies header attachment while delivering the structural performance and installation efficiency that demanding framing projects require.
Key Features
- No web stiffeners required in standard configurations - eliminates an extra installation step and keeps the framing process moving on commercial and high-load jobs.
- Positive-Angle Nailing (PAN) - allows nails to be driven at a more accessible and favorable angle, reducing the risk of I-joist flange splitting and speeding up the nailing process.
- Speed prongs for temporary positioning - hold the connector in place during installation so framers can work faster and with greater accuracy without needing a second set of hands.
- Face-mount design - attaches directly to the face of the header, making alignment straightforward and reducing layout time on structural framing assemblies.
- Optional triangle joist nail holes for added uplift capacity - provide flexibility to increase uplift resistance when project loads demand it, with web stiffeners required when using this option.
- Zinc Galvanized G90 coating - provides corrosion resistance suited to structural framing environments, supporting long-term connector integrity.
Why This Product
- Purpose-built for high-load and double I-joist applications - this hanger is engineered specifically for the heavier demands of commercial structural framing, not just light residential use, making it a dependable fit for more challenging projects.
- Faster installation without sacrificing performance - the combination of speed prongs, Positive-Angle Nailing, and a face-mount design means installers spend less time positioning and wrestling with hardware and more time completing the frame.
- Flexible uplift capacity for varying structural demands - the option to add joist nails through the triangle nail holes allows this single hanger model to adapt to projects with higher uplift requirements, reducing the need to source a different connector.
- Domestic manufacturing and consistent quality - produced in the United States by Simpson, a trusted name in structural connectors, this hanger brings reliability to specifications where product consistency matters.

Frequently Asked Questions
- Are web stiffeners required when using the MIU4.12/11?
- The MIU hanger is specifically designed for commercial, high-load, and double I-joist applications without requiring web stiffeners in standard configurations. However, when using the optional triangle joist nail holes for additional uplift, properly attached web stiffeners are required.
- What is Positive-Angle Nailing (PAN) and why does it matter?
- Positive-Angle Nailing (PAN) is a design feature of the MIU hanger that allows nails to be driven at a more favorable angle. This minimizes splitting of the I-joist flanges during installation while also saving time by letting the installer nail from a better, more accessible position.
- What is the uplift load capacity when using additional joist nails?
- By adding four additional 10dx1-1/2 in. joist nails through the optional triangle joist nail holes, the MIU4.12/11 can achieve a total uplift load of 975 lbs. Always use all specified fasteners and verify that the header can accommodate the required fasteners as specified in the load table.
- What coating does the MIU4.12/11 have, and what does it protect against?
- The MIU4.12/11 features a Zinc Galvanized G90 coating, which provides a layer of corrosion resistance suited for structural framing environments. Always confirm coating compatibility with the specific treated lumber or environmental conditions of your project.
