The Simpson BA5.12/9.5 Top-Flange Joist Hanger is a heavy-duty connector designed for double 2-1/2 in. x 9-1/2 in. engineered wood and solid sawn lumber framing connections. Built from 12-gauge steel with a G90 galvanized finish, this top-flange hanger supports medium loads with solid sawn lumber and higher loads with engineered wood products. The BA design accommodates both minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing for higher-load applications, giving framers the flexibility to meet a wide range of structural requirements in a single connector.

Key Features

• Cost-effective one-piece design - eliminates the added expense and potential weak points of welded hangers, delivering reliable structural integrity without unnecessary complexity.
• Full-height joist flange - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, reducing both material costs and installation steps.
• Dual nailing configurations (minimum PAN and maximum) - lets installers dial in the right load capacity for each application without switching to a different hanger model.
• Compatible with both engineered wood products and solid sawn lumber - provides flexibility across framing systems and job-site conditions without requiring separate connectors for each material type.
• 12-gauge steel construction - provides the thickness and rigidity needed to handle medium to higher structural loads in top-flange joist-to-header and joist-to-beam installations.
• G90 zinc galvanized finish - adds an extra layer of corrosion resistance, making this hanger suitable for applications where long-term durability matters.
• Available modified for sloped and/or skewed members - offers adaptability for non-standard framing angles, keeping the same trusted hanger design working across more complex framing layouts.

Why This Product

• One hanger, two load levels - the BA's support for both minimum PAN nailing and maximum nailing means a single connector model covers moderate and higher load demands, reducing the need to stock multiple hanger types for similar joist sizes.
• Built-in rotation control without extra hardware - the full-height joist flange captures the top chord and prevents joist rotation, removing the need for web stiffeners and simplifying the overall framing assembly.
• Engineered wood-ready performance - while capable of handling solid sawn lumber at medium loads, this hanger is specifically suited to carry higher loads when paired with engineered wood products, making it a strong match for modern framing where LVL and I-joist construction is common.
• Durable finish for long-term reliability - the G90 galvanized coating provides corrosion resistance that helps the connection maintain its structural integrity over the life of the building, without requiring additional protective treatment.
