Simpson Strong-Tie MIU3.56/9 - 3-1/2" x 9-1/2" Face Mount I-Joist Hanger
The MIU hanger is designed for commercial, high-load and double I-joist applications without requiring web stiffeners. The MIU features positive-angle nailing (PAN) which minimizes splitting of the flanges while permitting time-saving nailing from a better angle. This face-mount hanger features speed prongs to temporarily position and secure the connector for easier and faster installation.

Options
MIU hangers cannot be modified. However, these models will normally accommodate a skew of up to 5°. For sloped joists up to 1/4:12 there is no reduction; between 1/4:12 and up to 1/2:12, tests show a 10% reduction in ultimate hanger strength. Local crushing of the bottom flange or excessive deflection may be limiting; check with joist manufacturer for specific limitations on bearing of this type.
