Product Description
The Simpson 1-1/2 x 11-7/8 Top-Flange I-Joist Hanger is an 18-gauge, G90 zinc galvanized connector engineered by Simpson to deliver secure 90 deg. connections between I-joists and headers. Built around a Strong-Grip seat and Funnel Flange design, this top-flange hanger is purpose-built for contractors and builders who need a reliable, efficient solution for I-joist framing applications where a clean, structurally sound connection is non-negotiable.
Key Features
- Top-flange mounting configuration - seats the hanger over the header for a stable, positive connection that keeps the I-joist properly positioned during and after installation
- Strong-Grip seat design - provides secure, consistent joist seating so the joist stays firmly in place throughout the installation process, reducing the risk of shifting or misalignment
- Funnel Flange design allows installation without joist nails - simplifies the installation sequence and reduces both labor time and fastener costs on the job site
- 18-gauge steel construction with G90 zinc galvanized coating - delivers corrosion resistance suited for moisture-prone environments while maintaining the structural integrity the connection demands
- Sized specifically for 1 1/2 x 11-7/8 I-joists - eliminates guesswork by matching the hanger geometry precisely to the intended joist profile for a consistent, code-compliant fit
- Made in the United States - reflects Simpson quality standards from a domestically produced connector built to meet the demands of professional framing applications
Why This Product
- Lower installed cost without sacrificing performance - the Funnel Flange design eliminates the need for joist nails during installation, cutting both material and labor costs compared to conventional top-flange hanger approaches
- Engineered specifically for I-joist framing - unlike generic hangers, this connector is purpose-designed for the unique geometry of I-joists, ensuring a proper 90 deg. connection to the header every time
- Corrosion-resistant G90 zinc galvanized finish - makes this hanger a dependable choice in applications where long-term moisture exposure could compromise an uncoated connector
- Trusted Simpson engineering in a domestically produced connector - builders who rely on Simpson hardware for structural applications get the same brand consistency and quality control in this top-flange I-joist hanger
