The Simpson Double 1-1/2 x 9-1/2 Welded Top-Flange Joist Hanger WP29.5-2 from Simpson is an engineered metal connector built to support double 1 1/2 in. x 9 1/2 in. I-joists on purlins or beams across a broad range of structural framing applications. Constructed from 97 mil (12 ga.) steel and finished in Simpson Strong-Tie Gray Paint, this top-flange hanger accommodates wood-to-wood, wood-to-steel, and cold-formed steel connections, and handles skewed layouts up to 84 deg. and sloped installations up to 45 deg. - making it a highly adaptable solution for complex framing conditions.

Key Features

• Top-flange welded design - seats the joist flush against the carrier beam for a secure, stable bearing surface that simplifies installation and reduces movement in the finished assembly.
• Compatible with wood-to-wood, wood-to-steel, and cold-formed steel framing - gives builders and contractors the flexibility to use a single hanger type across multiple connection scenarios without sourcing different hardware.
• Accepts skew up to 84 deg. and slope up to 45 deg. - allows the hanger to accommodate angled and sloped framing layouts that straight hangers cannot handle, expanding its usefulness on non-standard or complex roof and floor structures.
• Supports double 1 1/2 in. x 9 1/2 in. I-joists on purlins or beams - engineered specifically for this member size, ensuring proper load transfer and a precise fit without field modification.
• 97 mil (12 ga.) stirrup construction - provides the material thickness needed for structural-grade performance in demanding residential and commercial framing applications.
• Simpson Strong-Tie Gray Paint finish - offers corrosion resistance suited to standard interior and protected framing environments, with hot-dip galvanized options available for projects requiring enhanced protection.

Why This Product

• Engineered for versatility in real-world framing - the combination of wide skew capacity (up to 84 deg.) and slope tolerance (up to 45 deg.) means this hanger works in the angled, irregular conditions that commonly arise in roof framing and multi-level floor systems, reducing the need for custom fabrication.
• Multi-substrate compatibility in one connector - by supporting wood-to-wood, wood-to-steel, and cold-formed steel connections, this hanger fits naturally into mixed-material builds and hybrid framing systems without requiring a different product for each substrate type.
• Trusted Simpson quality, made in the United States - backed by the engineering standards Simpson is known for, the WP29.5-2 delivers consistent dimensional accuracy and material quality that contractors can rely on from project to project.
• Purpose-built fit for double I-joist applications - designed specifically for double 1 1/2 in. x 9 1/2 in. members, this hanger eliminates guesswork around sizing and load path alignment, helping ensure code-compliant connections and a cleaner, faster install.
