The Simpson MIU2.37/20 Face-Mount I-Joist Hanger is a heavy-duty connector engineered to deliver reliable, high-load support for 2-5/16 in. x 20 in. I-joists in demanding commercial and residential framing applications. Built by Simpson with a 16-gauge zinc galvanized construction and a G90 coating, this face-mount hanger is designed for double I-joist installations, high-load floor and roof framing systems, and commercial applications where consistent structural performance and installation efficiency are equally critical.

Key Features

• No web stiffeners required in standard use - simplifies installation and reduces material prep time, keeping large-scale framing projects on schedule without sacrificing structural integrity.
• Face-mount design with positive-angle nailing geometry - allows fasteners to be driven at an angle that protects I-joist flanges from splitting, resulting in cleaner, safer connections in both floor and roof framing assemblies.
• Optional triangle joist nail holes for added uplift resistance - gives installers the flexibility to increase uplift capacity when project conditions demand it, provided web stiffeners are properly attached as required.
• G90 zinc galvanized coating - provides a durable corrosion-resistant finish suited for the environmental demands of commercial and light commercial construction environments.
• Approved for double I-joist hanger installations - accommodates doubled framing members in high-load scenarios, reducing the need for custom or specialty hardware on complex framing layouts.
• Designed and produced in the United States - reflects consistent quality standards aligned with North American commercial framing requirements.

Why This Product

• Handles the toughest framing demands without added complexity - rated for commercial, high-load, and double I-joist applications, this hanger covers a wide range of structural scenarios without requiring additional reinforcement components in standard configurations.
• Protects the joist during fastening - the face-mount, positive-angle nailing approach is specifically chosen to reduce the risk of flange damage during installation, which is a common concern when working with engineered lumber in large-format sizes like 2-5/16 in. x 20 in.
• Scalable uplift performance - the optional triangle nail holes allow uplift capacity to be increased when needed, giving builders a single hanger model that adapts to varying load requirements rather than requiring a different product for higher-uplift applications.
• Built by a trusted name in structural connectors - Simpson brings recognized expertise to this hanger's engineering, giving contractors and engineers confidence when specifying it for commercial framing, high-load residential builds, and light commercial roof systems.

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.
