The Simpson BA Top-Flange Joist Hanger for 3-1/2 in. x 11-7/8 in. Engineered Wood from Simpson is a heavy-duty, single-piece connector engineered for both engineered wood and solid sawn lumber framing applications. This top-flange hanger carries medium loads with solid sawn lumber and higher loads with engineered wood products, giving contractors and builders the flexibility to handle a range of structural conditions with a single reliable solution. The BA series supports minimum nailing with positive-angle nailing (PAN) to target moderate load conditions, and maximum nailing to support higher loads, so the connection can be configured to match the demands of the job.

Key Features

• Cost-effective one-piece design compared to welded hangers - eliminates the added expense and complexity of multi-piece or welded alternatives, reducing both material and labor costs on the job site.
• Full-height joist flange captures the top chord of the joist - prevents joist rotation and eliminates the need for web stiffeners, saving installation steps while maintaining structural integrity.
• Positive-angle nailing (PAN) with flexible nailing options - minimum nailing addresses moderate load conditions while maximum nailing supports higher loads, allowing the same hanger to adapt to varying project requirements.
• Compatible with both engineered wood and solid sawn lumber - delivers medium load capacity with solid sawn lumber and higher load capacity with engineered wood products, making it a versatile choice across different framing scenarios.
• Made from 14-gauge steel with a Zinc Galvanized (G90) finish - provides the structural strength and corrosion resistance needed for long-term performance in demanding framing environments.
• Available for sloped and/or skewed applications - accommodates non-standard framing angles, reducing the need to source specialty connectors for complex roof or floor framing conditions.

Why This Product

• One connector, two lumber types - because the BA hanger performs with both engineered wood products and solid sawn lumber, framing crews can rely on a single connector family across mixed-material projects rather than stocking multiple hanger types.
• Built-in rotation control without extra hardware - the full-height joist flange captures the top chord and eliminates the need for web stiffeners, reducing part count and simplifying the installation process without compromising load performance.
• Scalable load performance through nailing - the ability to shift between minimum and maximum nailing patterns means the same hanger can be dialed in for moderate or higher load conditions, offering genuine on-site flexibility backed by Simpson engineering.
• Corrosion-resistant construction for lasting durability - the G90 Zinc Galvanized coating protects the 14-gauge steel connector against corrosion, supporting long-term structural reliability in the environments where beam hangers and joist connectors are most commonly exposed to moisture.

Frequently Asked Questions

What types of lumber is the BA3.56/11.88 hanger compatible with?

The BA3.56/11.88 is designed for both engineered wood and solid sawn lumber applications. It carries medium loads with solid sawn lumber and higher loads with engineered wood products.

What steel gauge and coating does this hanger use?

This hanger is made from 14-gauge steel with a Zinc Galvanized (G90) coating, providing extra corrosion resistance for long-term durability in framing applications.

What fasteners are required to install the BA3.56/11.88?

Installation requires 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 1-1/2 in. nails in the joist. The hanger supports both minimum nailing with positive-angle nailing (PAN) for moderate loads and maximum nailing for higher loads.

Does the full-height joist flange provide any structural advantages?

Yes. The full-height joist flange captures the top chord of the joist to prevent rotation and eliminates the need for web stiffeners, simplifying installation while maintaining structural integrity.
