The Simpson BA3.56/28 Top-Flange Joist Hanger is built for engineered wood and solid sawn lumber framing applications where reliable load transfer and joist stability are critical. Sized to fit a 3-1/2 in. x 28 in. member, this top-flange hanger delivers medium load capacity with solid sawn lumber and higher load capacity when paired with engineered wood products. The BA series supports flexible nailing configurations - minimum nailing with positive-angle nailing (PAN) for moderate load conditions, and maximum nailing to handle higher structural demands - making it a practical, performance-ready choice for a wide range of residential and commercial framing projects.

Key Features

• Cost-effective one-piece design - eliminates the added expense and complexity of welded hangers, reducing both material and installation costs without compromising structural integrity
• Full-height joist flange - captures the top chord of the joist to actively prevent rotation and eliminate the need for web stiffeners, simplifying installation and reducing additional hardware requirements
• Flexible nailing options (PAN and maximum nailing) - lets builders match the fastening schedule to the load condition, supporting both moderate and higher structural demands with a single hanger design
• 12-gauge steel construction - provides a robust, heavy-duty foundation suited for the load demands of engineered lumber connections in structural framing
• G90 zinc galvanized finish - offers enhanced corrosion resistance, extending service life in environments where moisture exposure is a concern
• Available with slope and skew modifications - accommodates non-standard framing angles (slopes up to 45 deg., top flanges sloped up to 35 deg., open or closed up to 30 deg.), adding versatility for complex structural layouts

Why This Product

• Engineered for high-load engineered wood applications - the BA design is specifically optimized to carry higher loads when used with engineered wood products, making it a strong fit for modern floor systems and heavy-span framing where performance demands exceed what standard hangers typically address
• One-piece construction cuts labor and material costs - unlike welded alternatives, this hanger arrives ready to install as a single unit, reducing the number of components on the job site and speeding up the framing process
• Rotation prevention built into the design - the full-height joist flange locks the top chord in place, eliminating joist rotation without requiring additional web stiffeners, which translates directly to fewer steps and less material during installation
• Adaptable to a wide range of framing conditions - with support for sloped, skewed, and standard configurations alongside scalable nailing options, this hanger works across varied structural layouts without requiring a different product for each scenario

Approved Applications

• Engineered wood products - suited for higher load demands when used with engineered lumber
• Solid sawn lumber - suitable for medium load applications
• Top-flange framing connections where joist rotation prevention is required
• Applications requiring flexible nailing - minimum nailing (PAN) for moderate loads; maximum nailing for higher loads

Installation

Install with 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 full-height joist flange captures the top chord of the joist, preventing rotation and eliminating the need for web stiffeners during installation.

Options

• Other widths are available; specify W dimension (the minimum W dimension is 1 9/16").
  
• For modified hangers, fastener quantity listed in tables may need to increase depending on joist size, skew and slope. All modified hangers are 12 ga.
• Hangers may be modified for slopes and/or skews up to 45 deg.. The top flanges may be sloped as much as 35 deg. and may be open or closed up to 30 deg.. See Modifications and Associated Load Reductions under Specifications
