The Simpson WP9 Welded Top-Flange Joist Hanger is a 1-3/4 x 9-1/2 structural connector engineered by Simpson to deliver reliable joist support across a wide range of framing conditions. Whether connecting wood-to-wood, wood-to-steel, or cold-formed steel framing, this hanger is built to handle both standard layouts and complex angled configurations - including skewed framing up to 84 deg. and sloped installations up to 45 deg. - without sacrificing structural integrity or installation efficiency.

Key Features

• Top-flange design - secures directly to the top of the supporting member, providing solid bearing and simplifying installation in tight framing situations
• Skew capability up to 84 deg. - accommodates severely angled framing layouts, giving builders the flexibility to handle complex structural geometries without custom fabrication
• Slope capability up to 45 deg. - supports pitched or sloped roof and floor framing conditions, making this hanger suitable for a broad range of residential and commercial applications
• Heavy-gauge 97 mil (12 ga.) stirrup material - delivers the structural strength needed to meet demanding load requirements in wood and cold-formed steel framing systems
• Multi-application approval - rated for wood-to-wood, wood-to-steel, and cold-formed steel connections, reducing the need to source different hangers for different framing scenarios
• Simpson Gray Paint finish - provides a consistent, corrosion-resistant base coating suited for protected interior framing environments, with hot-dip galvanized options available for projects requiring enhanced corrosion resistance

Why This Product

• Engineered for versatility across framing types - approved for wood-to-wood, wood-to-steel, and cold-formed steel framing applications, this hanger covers the widest range of structural scenarios a contractor or builder is likely to encounter on a single job site
• Handles extreme angles without compromise - with skew capability up to 84 deg. and slope capability up to 45 deg., the WP9 eliminates the need for field-fabricated solutions when framing layouts deviate from standard perpendicular connections
• Built to Simpson's heavy-gauge standard - the 97 mil (12 ga.) stirrup construction reflects the same commitment to load-carrying performance that professionals have come to expect from Simpson structural connectors
• Domestically produced quality - manufactured in the United States, the WP9 is held to consistent production standards that support confidence in performance and material integrity on every project
