The Simpson 1 1/2 x 9 1/2 Top Flange I-Joist Hanger from Simpson is a welded top-flange connector engineered to support joists on purlins or beams across a wide range of structural framing conditions. With a robust welded stirrup construction and a top-flange design, this hanger is built to handle wood-to-wood, wood-to-steel, and cold-formed steel framing applications while accommodating demanding skewed and sloped layouts - making it a reliable choice for both standard and complex joist installations.

Key Features

• Welded Top-Flange Construction - The welded stirrup design delivers high download capacity with a minimal number of fasteners, helping reduce installed labor costs without sacrificing structural performance.
• Broad Framing Compatibility - Approved for wood-to-wood, wood-to-steel, and cold-formed steel framing connections, giving contractors and builders flexibility across a wide variety of project types and structural assemblies.
• High Skew Tolerance up to 84 deg. - Accommodates heavily skewed framing layouts, eliminating the need for custom-cut blocking or field fabrication in complex roof and floor framing geometries.
• Slope Capacity up to 45 deg. - Handles steeply sloped framing configurations, making this hanger well suited for cathedral ceilings, pitched roofs, and other angled structural applications.
• Heavy-Gauge 12 ga. Steel Stirrup - The 97 mil stirrup thickness provides the material strength needed to meet demanding load requirements in residential and light commercial framing situations.
• Simpson Strong-Tie Gray Paint Finish - The factory-applied finish provides a base level of corrosion resistance for interior and protected framing applications, with hot-dip galvanized models available for projects requiring enhanced protection.

Why This Product

• Engineered for Versatility - Support for wood-to-wood, wood-to-steel, and cold-formed steel connections in a single hanger model means fewer SKUs to source and greater adaptability across different framing systems on the same job site.
• Handles Extreme Angles with Confidence - The combined skew capacity of up to 84 deg. and slope capacity of up to 45 deg. makes this hanger one of the most geometry-flexible connectors available for purlin and beam joist support, reducing the need for field modifications.
• Lower Installed Cost Through Efficient Fastening - The welded construction and top-flange configuration are specifically designed to achieve maximum download capacity with fewer nails or screws, directly cutting installation time and hardware expense.
• Trusted Simpson Engineering - Built to the standards that structural professionals rely on, this hanger reflects the same quality and engineering discipline found across the full Simpson connector line for framing applications.
