The Simpson 2-5/16 x 20 Top-Flange I-Joist Hanger is a welded, top-flange connector engineered by Simpson to support joists on purlins or beams across a broad range of structural framing conditions. Built from 97 mil (12 ga.) steel and finished in Simpson Strong-Tie Gray Paint, this hanger is designed for wood-to-wood, wood-to-steel, and cold-formed steel framing applications, making it a practical choice for contractors and structural engineers working with varied connection types on the same job.

Key Features

• Welded Top-Flange Design - seats securely over the top of the supporting member, reducing installation steps and keeping the hanger positively located during framing.
• Skew Capacity up to 84 deg. - accommodates highly angled framing layouts without requiring custom fabrication, saving time on complex structural configurations.
• Slope Capacity up to 45 deg. - handles steeply pitched roof and floor framing conditions in a single connector, eliminating the need to source specialty slope hangers for most applications.
• Compatible with Multiple Connection Types - approved for wood-to-wood, wood-to-steel, and cold-formed steel framing connections, giving builders flexibility across different structural assemblies on the same project.
• 97 mil (12 ga.) Steel Construction - provides a robust stirrup gauge appropriate for the large 2-5/16 in. x 20 in. joist size this hanger is specifically sized to carry.
• Simpson Strong-Tie Gray Paint Finish - offers a corrosion-resistant baseline finish suitable for protected interior framing environments, with hot-dip galvanized availability for more demanding exposure conditions.
• Made in the United States - produced domestically, supporting consistent quality control and reliable material traceability for specification-sensitive projects.

Why This Product

• One hanger, multiple framing scenarios - the combination of up to 84 deg. skew and up to 45 deg. slope capacity means this welded top-flange hanger covers a wide spectrum of structural framing layouts without requiring multiple connector models on the same job site.
• Sized for large engineered lumber - purpose-built for a 2-5/16 in. x 20 in. joist, this connector is properly matched to the deep I-joist and LVL members commonly used in longer-span floor and roof framing systems.
• Cross-material compatibility - tested and approved for wood-to-wood, wood-to-steel, and cold-formed steel connections, giving structural engineers and framers a single, specification-ready solution across different supporting member materials.
• Trusted Simpson engineering - manufactured by Simpson, a brand widely recognized in the structural connector industry, giving specifiers and inspectors a familiar, well-documented product for permit-required framing work.
