The Simpson BA3.56/20 BA Top-Flange Joist Hanger for 3-1/2 in. x 20 in. Engineered Wood from Simpson is a versatile framing connector engineered for both engineered wood and solid sawn lumber applications. This top-flange hanger carries medium loads with solid sawn lumber and higher loads with engineered wood products, making it a dependable choice for a wide range of structural framing conditions. Flexible nailing options - minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing for higher loads - give builders precise control over load management on any job site.

Key Features

• Cost-effective one-piece design compared to welded hangers - reduces material complexity and installation time without sacrificing structural performance.
• Full-height joist flange captures the top chord of the joist - prevents rotation and eliminates the need for web stiffeners, simplifying the installation process.
• Positive-angle nailing (PAN) support - allows minimum nailing for moderate load conditions and maximum nailing for higher loads, giving installers flexibility to match the hanger to the specific structural demand.
• Made from 12-gauge steel - provides the structural rigidity needed to handle medium to higher load capacities across engineered wood and solid sawn lumber framing applications.
• Zinc Galvanized, G90 coating - delivers extra corrosion resistance, helping the hanger hold up in demanding installation environments over the long term.
• Available for special order to accommodate sloped and/or skewed members - makes this hanger adaptable to non-standard framing configurations where angled connections are required.

Why This Product

• Dual compatibility with engineered wood and solid sawn lumber - one hanger handles both material types, reducing the need to source different connectors for mixed-material framing projects.
• One-piece construction eliminates the cost and complexity of welded hangers - the single-piece design streamlines procurement and speeds up installation, keeping labor and material costs in check.
• Rotation prevention built in by design - the full-height joist flange captures the top chord and removes the need for web stiffeners, cutting out extra hardware and extra steps during framing.
• Scalable load performance through nailing options - by switching between minimum PAN nailing and maximum nailing, the same hanger can be configured for moderate or higher load demands without requiring a different product.
