The Simpson IUS1.81/9.5 Face-Mount Joist Hanger is a hybrid connector from Simpson that brings together the strengths of both face-mount and top-mount hanger designs into a single, versatile solution sized for 1-3/4 in. x 9-1/2 in. engineered wood I-joists. Fully compatible with shallow-flange I-joists, this hanger is built for framing professionals who need a fast, reliable connection at the header without sacrificing structural integrity. Its Strong-Grip seat lets the I-joist snap securely into place, streamlining the installation process on the job site.

Key Features

• Strong-Grip seat with self-jigging locator tabs - allows the I-joist to snap firmly into position for fast, accurate placement that reduces installation time and minimizes alignment errors
• Easy-to-reach face nail locations - simplifies fastening so crews can drive nails quickly and confidently without awkward repositioning
• Hybrid face-mount and top-mount design - gives installers greater flexibility and a secure connection that works with shallow-flange I-joists where standard hangers may not perform as well
• 18-gauge steel construction - provides a durable, rigid hanger body that holds its shape during and after installation
• G90 zinc galvanized coating - delivers extra corrosion resistance, making this hanger a dependable choice in framing applications where moisture exposure is a concern
• Installs with 10d common nails - uses a widely available fastener type so there is no need to source specialty hardware

Why This Product

• Purpose-built for engineered wood I-joists - the IUS series is fully compatible with shallow-flange I-joists and accepts a 1-3/4 in. x 9-1/2 in. member exactly, eliminating guesswork and reducing the risk of a poor fit when working with engineered lumber
• Faster installation without sacrificing connection quality - the Strong-Grip seat, self-jigging locator tabs, and easy-to-reach face nails work together so the hanger goes up quickly and securely, helping crews move through framing with fewer delays
• One hanger, two mounting advantages - the hybrid design incorporates the benefits of both face-mount and top-mount approaches, giving contractors a more flexible connection option compared to single-style hangers
