The Simpson BA3.56/28 BA Top-Flange Joist Hanger is engineered for use with both engineered wood products and solid sawn lumber applications. Designed 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 features flexible nailing options - minimum nailing with positive-angle nailing (PAN) for moderate load conditions, and maximum nailing configurations to support higher structural demands - making it a versatile, performance-driven solution for a wide range of framing applications.

Key Features

• Cost-effective one-piece design compared to welded hangers - reducing material and labor costs without sacrificing performance
• Full-height joist flange captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners
• Positive-angle nailing (PAN) supports minimum nailing for moderate load conditions; maximum nailing available for higher load requirements
• 12-gauge steel construction provides robust structural integrity for demanding framing applications
• G90 Zinc Galvanized finish delivers enhanced corrosion resistance for long-term durability
• Accommodates sloped and/or skewed members - available for special order configurations (see Options below)
• Actual joist size: 3-1/2 in. x 28 in.
• Made in the United States

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

Frequently Asked Questions

What size joist is the BA3.56/28 designed to fit?

This hanger is designed to fit a joist with an actual member size of 3-1/2 in. x 28 in., making it suitable for use with engineered wood products and solid sawn lumber of that dimension.

What type of nails are required to install this hanger?

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.

Does this hanger work with both engineered wood and solid sawn lumber?

Yes. The BA3.56/28 is compatible with both engineered wood products and solid sawn lumber. It carries medium loads with solid sawn lumber and higher loads when used with engineered wood products. Minimum nailing with positive-angle nailing (PAN) supports moderate load conditions, while maximum nailing configurations accommodate higher structural demands.

What corrosion protection does this hanger have, and what is it made from?

The BA3.56/28 is made from 12-gauge steel and features a G90 Zinc Galvanized finish, which provides extra corrosion resistance for long-term durability in framing applications.
