The Simpson MIU4.28/16 Face-Mount I-Joist Hanger is a heavy-duty structural connector from Simpson built specifically for commercial and high-load engineered wood I-joist applications. Engineered to cradle and support the joist from below, this face-mount hanger delivers a strong, reliable connection for 4-1/8 in. x 16 in. I-joists without requiring web stiffeners - simplifying installation while maintaining structural integrity. Its positive-angle nailing technology and robust 16-gauge galvanized steel construction make it a dependable choice for demanding framing projects.

Key Features

• Positive-angle nailing minimizes splitting of the flanges while permitting time-saving nailing from a better angle - reducing the risk of joist damage during installation and helping crews work faster with less effort
• Designed for commercial and high-load I-joist applications without requiring web stiffeners - cuts down on labor steps and extra materials, keeping your project on schedule
• Made from 16-gauge steel - provides the structural strength and rigidity needed to handle demanding load requirements in commercial framing
• Galvanized finish with G90 coating - delivers enhanced corrosion resistance to help the hanger hold up in moisture-prone environments over the long term
• These hangers cannot be modified - ensures the connector is always used as engineered, protecting rated performance and code compliance on every installation

Why This Product

• Built for high-load commercial work without added complexity - the MIU series is designed specifically for heavy I-joist applications and eliminates the need for web stiffeners, meaning fewer parts to manage and a cleaner, faster install
• Positive-angle nailing saves real time on the job - by allowing fasteners to be driven from a more accessible angle, this hanger reduces nailing difficulty and helps minimize flange splitting, protecting the integrity of your engineered lumber
• Heavy-gauge, corrosion-resistant construction you can count on - 16-gauge steel paired with a G90 galvanized coating means this connector is built to perform in tough conditions, not just on paper
• A precision fit for 4-1/8 in. x 16 in. engineered I-joists - manufactured to exact dimensions for its intended joist size, this hanger installs as designed with no field modification required, supporting consistent, code-compliant results across the project
