The Simpson MIU4.12/16 Face-Mount I-Joist Hanger is an engineered connector built for commercial framing, high-load joist connections, and double I-joist applications. Sized for a 4 in. x 16 in. I-joist, this face-mount hanger is designed to perform in demanding structural environments where reliable load transfer and installation efficiency are priorities. Its engineering eliminates the need for web stiffeners in standard installation, keeping workflows moving on busy job sites.

Key Features

• No Web Stiffeners Required - standard installation skips this extra step, reducing labor time and simplifying the framing process on commercial and high-load projects.
• Positive-Angle Nailing Technology - drives nails at an optimized angle that minimizes flange splitting and makes nailing faster and more ergonomic for the installer.
• Speed Prongs - temporarily hold the hanger in position during installation, freeing up hands and cutting setup time on the job site.
• Optional Triangle Joist Nail Holes - allow for additional uplift resistance when properly attached web stiffeners are used, expanding the hanger's performance range for uplift-critical connections.
• Zinc Galvanized G90 Coating - provides a corrosion-resistant finish suited for the structural demands of commercial construction environments.
• Face-Mount Design - connects directly to the header face, making it well suited for header-to-joist connections where accessibility and a clean structural tie are required.

Why This Product

• Engineered for Commercial-Grade Demands - this hanger is purpose-built for high-load single and double I-joist applications, making it a dependable choice when residential-grade hardware is not sufficient for the scope of the project.
• Faster Installation Without Compromising Structural Integrity - the combination of speed prongs and no-web-stiffener installation reduces the steps required to set and secure the hanger, helping crews maintain pace on large framing jobs.
• Versatile Uplift Options - the optional triangle joist nail holes allow contractors to increase uplift capacity when project conditions call for it, giving this single connector the flexibility to serve a wider range of connection requirements.
• Simpson Quality, Domestic Production - backed by Simpson engineering and produced in the United States, this face-mount I-joist hanger is built to meet the expectations of structural professionals working in demanding commercial construction settings.
