The Simpson Double 2-5/16 x 9-1/2 Welded Top-Flange Joist Hanger is a heavy-duty connector engineered to deliver dependable joist support where framing members meet purlins or beams. Built from 97 mil (12 ga.) steel with a welded construction, this top-flange hanger accommodates wood-to-wood, wood-to-steel, and cold-formed steel framing applications, making it a practical solution for a broad range of floor and roof assembly conditions. Its capacity to skew up to 84 deg. and slope up to 45 deg. means complex or irregular framing layouts are handled without compromising structural integrity.

Key Features

• Welded top-flange construction - provides a rigid, secure connection at the bearing point, reducing movement and delivering consistent load transfer onto purlins or beams.
• 97 mil (12 ga.) steel stirrup - heavy-gauge material ensures the hanger maintains its shape and strength under demanding structural loads in both floor and roof framing.
• Skewable up to 84 deg. left or right - accommodates angled framing layouts that would otherwise require custom fabrication, saving time and reducing field modifications.
• Slopes up to 45 deg. - supports pitched roof and floor assemblies within a single product, eliminating the need for separate sloped-specific hardware in most applications.
• Compatible with wood-to-wood, wood-to-steel, and cold-formed steel connections - versatility across substrate types means fewer SKUs to stock and a single hanger solution for mixed-material framing projects.
• Simpson Strong-Tie Gray Paint finish - factory-applied coating provides a baseline level of corrosion resistance suitable for standard interior framing environments.

Why This Product

• Engineered for demanding double-joist applications - the double 2-5/16 x 9-1/2 configuration is purpose-built to carry the combined load of paired joists at a single bearing point, giving structural designers a reliable, tested solution for high-load framing conditions.
• Exceptional installation flexibility - with skew capacity up to 84 deg. and slope capacity up to 45 deg., this hanger adapts to complex roof and floor geometries that would typically require field-fabricated or custom connectors.
• Multi-application compatibility - approved for wood-to-wood, wood-to-steel, and cold-formed steel framing, this hanger works across the material combinations commonly encountered in commercial and residential construction, reducing the need to source multiple connector types.
• Backed by Simpson quality - manufactured under the Simpson brand, this hanger reflects the engineering standards and quality controls that structural contractors and engineers rely on for code-sensitive framing connections.
