The Simpson Welded Top-Flange Joist Hanger is an engineered structural connector built to support joists on purlins or beams across a broad range of residential and commercial framing applications. Fabricated with a welded construction, the WP610 handles wood-to-wood, wood-to-steel, and cold-formed steel configurations from a single connector, eliminating the need for multiple hanger types on complex projects. Its capacity to accommodate extreme skew and slope angles makes it a dependable choice for challenging framing layouts where standard hangers fall short.

Key Features

• Wide Skew Range - Accommodates skew up to 84 deg., giving framers the flexibility to achieve precise joist alignment in angled and non-orthogonal layouts without cutting or fabricating custom hardware.
• Generous Slope Capacity - Handles slopes up to 45 deg., making this hanger equally suited to sloped roof assemblies and angled floor joist installations.
• Multi-Material Compatibility - Approved for wood-to-wood, wood-to-steel, and cold-formed steel applications, reducing the number of different connectors a contractor needs to keep on hand.
• Welded Construction - The welded stirrup design provides consistent structural integrity and reliable load transfer at the joist-to-beam connection without field assembly of multiple components.
• Heavy-Gauge Stirrup Material - Constructed from 97 mil (12 ga.) steel, delivering the load capacity expected in demanding residential and commercial structural framing.
• Simpson Strong-Tie Gray Paint Finish - The factory-applied finish provides corrosion resistance suitable for typical interior framing environments, helping the connector maintain long-term structural performance.

Why This Product

• One connector, multiple framing scenarios - Support for wood-to-wood, wood-to-steel, and cold-formed steel connections means this single hanger type covers the mixed-material assemblies common in modern commercial and residential construction.
• Engineered for extreme angles - With skew capacity up to 84 deg. and slope capacity up to 45 deg., this hanger addresses the most demanding framing geometries that would require custom or specialty connectors from other product lines.
• Trusted Simpson engineering - Designed and produced by Simpson, a recognized name in structural connectors, the WP610 is built to consistent manufacturing standards that engineers and inspectors rely on for code-sensitive structural connections.
• Made in the United States - Domestic production supports consistent quality control and material traceability, which matters on projects where documentation and sourcing standards are closely scrutinized.
