The Simpson MIU4.12/16 Face-Mount I-Joist Hanger is an engineered connector purpose-built for commercial, high-load, and double I-joist applications without requiring web stiffeners. Sized for a 4-inch x 16-inch joist, this heavy-duty hanger features Positive-Angle Nailing (PAN) technology that minimizes flange splitting while allowing faster, ergonomically improved nailing. Speed prongs temporarily position and secure the connector during installation, significantly reducing setup time on the job site. Manufactured in the United States and finished with a zinc galvanized G90 coating, the MIU4.12/16 delivers reliable structural performance in demanding construction environments.

Key Features

• No Web Stiffeners Required: Designed for commercial, high-load, and double I-joist applications without the need for web stiffeners, streamlining installation.
• Positive-Angle Nailing (PAN): Allows nailing from a more favorable angle, minimizing splitting of the I-joist flanges while saving time on the job.
• Speed Prongs: Temporarily positions and secures the hanger to the header, enabling easier, faster single-handed installation.
• Optional Triangle Joist Nail Holes: Provides additional uplift capacity when needed for enhanced structural performance.
• Zinc Galvanized G90 Coating: Offers corrosion resistance suitable for a wide range of construction environments.
• Domestic Manufacturing: Made in the United States to consistent quality standards.
• Face-Mount Design: Installs directly to the face of the header for straightforward, secure attachment.
