The Simpson IUS3.56/9.5 Face-Mount Joist Hanger is a hybrid connector engineered by Simpson to support 3-1/2 in. x 9-1/2 in. engineered wood members, including shallow-flange I-joists. By combining the advantages of both face-mount and top-mount hanger designs, the IUS series delivers a fast, secure connection that keeps framing projects moving efficiently in residential and light commercial construction. Built from 18-gauge steel with a G90 zinc galvanized finish, this joist hanger is made to hold up in demanding conditions while simplifying the installation process from start to finish.

Key Features

• Strong-Grip seat with self-jigging locator tabs - the I-joist snaps firmly into place without joist nails, reducing installation steps and speeding up the overall framing process
• Easy-to-reach face nail locations - fasteners are positioned for convenient access, so installers spend less time maneuvering and more time completing the job
• Hybrid face-mount and top-mount design - fully compatible with shallow-flange I-joists, giving framers greater flexibility across a wider range of engineered wood applications
• 18-gauge steel construction - provides a sturdy, reliable connection that meets the structural demands of floor and roof framing assemblies
• G90 zinc galvanized finish - delivers enhanced corrosion resistance, helping the hanger maintain its integrity in moisture-prone environments over the long term
• Installs with 10d common nails - uses a standard, widely available fastener type so there is no need to source specialty hardware before getting to work

Why This Product

• Faster installation, lower labor cost - the Strong-Grip seat lets the I-joist snap into place and eliminates the need for joist nails at the seat, cutting steps out of every hanger installation on the job
• Engineered specifically for shallow-flange I-joists - the IUS series is fully compatible with engineered lumber that standard hangers may not accommodate, making it a dependable choice for modern framing with manufactured wood products
• Corrosion-resistant finish for lasting performance - the G90 zinc galvanized coating provides an added layer of protection against moisture and oxidation, keeping the connection sound in environments where bare steel would degrade
• Trusted Simpson engineering in a single-piece hybrid hanger - the IUS design merges the benefits of two hanger styles into one connector, reducing the need to stock multiple hanger types for different framing scenarios
