The Simpson MIU2.37/20 Face-Mount I-Joist Hanger is engineered for demanding commercial, high-load, and double I-joist applications, delivering exceptional structural performance without requiring web stiffeners in standard configurations. Designed to accommodate a 2-5/16 in. x 20 in. joist size, this heavy-duty 16-gauge zinc galvanized hanger brings together advanced nailing geometry and intuitive installation features to keep projects moving efficiently and safely. Whether you're working on large-scale commercial framing or tackling high-load residential builds, the MIU2.37/20 is built to meet the challenge with precision-engineered construction and a durable G90 galvanized coating.

Key Features

• No Web Stiffeners Required (Standard Use): The MIU hanger is designed for commercial, high-load, and double I-joist applications without requiring web stiffeners, streamlining installation and reducing material overhead.
• Positive-Angle Nailing (PAN): The innovative PAN design minimizes splitting of the I-joist flanges while permitting time-saving nailing from a better angle, improving both speed and structural integrity on the job site.
• Speed Prongs for Faster Positioning: Built-in speed prongs temporarily position and secure the connector to the header, enabling easier and faster installation without the need for additional holding methods during fastening.
• 16-Gauge Steel Construction: Heavy 16-gauge steel provides the structural rigidity needed for high-load commercial and multi-joist applications.
• G90 Zinc Galvanized Coating: The G90 galvanized finish delivers corrosion resistance suited for a wide range of building environments.
• Optional Triangle Joist Nail Holes: Models include optional triangle joist nail holes for additional uplift capacity when project requirements demand it.
• Made in the United States: Manufactured domestically to consistent quality standards.

Frequently Asked Questions

What joist size is the MIU2.37/20 designed to accommodate?

The MIU2.37/20 is designed to accommodate a 2-5/16 in. x 20 in. joist size, making it suitable for large-format I-joist applications in commercial and high-load framing scenarios.

Does the MIU2.37/20 require web stiffeners during installation?

No, in standard use configurations the MIU2.37/20 does not require web stiffeners. This design choice streamlines installation and reduces the amount of additional material needed on the job site.

What is the gauge and finish of the steel used in this hanger?

The MIU2.37/20 is constructed from 16-gauge steel with a G90 zinc galvanized coating, providing the structural rigidity needed for heavy-duty commercial and high-load applications along with corrosion resistance.

What installation features help speed up the fastening process on the job site?

The MIU2.37/20 includes two key features that improve installation efficiency: built-in speed prongs that temporarily position and secure the connector to the header without additional holding methods, and a Positive-Angle Nailing (PAN) design that allows nailing from a more accessible angle while also minimizing splitting of the I-joist flanges.
