The Simpson BA3.56/11.25 Top-Flange Joist Hanger is a one-piece structural connector designed for use with 3-1/2 in. x 11-1/4 in. engineered wood products and solid sawn lumber. Built to handle medium loads with solid sawn lumber and higher loads with engineered wood framing, this hanger supports a range of structural conditions through two nailing configurations: minimum nailing with positive-angle nailing (PAN) for moderate load conditions, and maximum nailing for heavier load demands. The 12-gauge steel construction and G90 zinc galvanized finish deliver durability suited to demanding framing applications.

Key Features

• Top-flange installation with full-height joist flange - captures the top chord of the joist to prevent rotation and eliminates the need for web stiffeners, reducing labor and hardware costs
• Positive-angle nailing (PAN) with flexible load configurations - supports both moderate and higher load conditions in a single hanger design, giving installers more versatility without switching products
• One-piece stamped construction - more cost-effective than welded hangers while maintaining consistent structural performance across engineered wood and solid sawn lumber connections
• Compatible with sloped and skewed framing members - available for special configurations to accommodate angled connections where standard square installation does not apply
• 12-gauge steel with G90 zinc galvanized coating - provides extra corrosion resistance, making this hanger suitable for applications where long-term durability is a priority
• Made in the United States - manufactured to consistent quality standards for structural connector applications

Why This Product

• Two nailing options in one hanger - the BA3.56/11.25 supports both minimum PAN nailing for moderate loads and maximum nailing for higher loads, so contractors can adapt to varying structural requirements without stocking multiple hanger types
• Eliminates the need for web stiffeners - the full-height joist flange locks the joist in place and prevents rotation, cutting down on extra material and installation steps in engineered wood framing
• Engineered wood and solid sawn lumber compatibility - a single connector works across both lumber types, making it a practical choice for mixed-framing projects or job sites where material specifications may vary
• Cost-effective one-piece design - delivers reliable structural performance without the added expense of welded alternatives, helping keep framing budgets on track without compromising connection integrity

Frequently Asked Questions

What size joist is this hanger designed to fit?

The BA3.56/11.25 is designed to fit a joist with an actual size of 3-1/2 in. x 11-1/4 in. It is compatible with both engineered wood products and solid sawn lumber of that dimension.

What nails should be used to install this hanger?

Install this hanger using 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.

Can this hanger be used for sloped or skewed installations?

The standard BA3.56/11.25 is designed for square installations, but it is available as a special order to accommodate sloped and/or skewed members if your application requires angled connections.

What material and coating is this hanger made from, and why does it matter?

This hanger is made from 12-gauge steel with a G90 zinc galvanized finish. The G90 galvanized coating provides extra corrosion resistance, making it suitable for applications where moisture exposure is a concern. Its one-piece construction also makes it a cost-effective alternative to welded hangers.
