The Simpson BA1.56/11.88 Top-Flange Joist Hanger is a versatile structural connector designed for both engineered wood products and solid sawn lumber framing applications. Built from 12-gauge steel with a Zinc Galvanized (G90) coating, this top-flange hanger fits a 1 1/2 in. x 11 7/8 in. member and delivers medium-to-high load capacity through a flexible nailing approach - minimum nailing with positive-angle nailing (PAN) for moderate load conditions, or maximum nailing to support higher loads. The full-height joist flange captures the top chord of the joist, preventing rotation and eliminating the need for web stiffeners across a wide range of structural framing connections.

Key Features

• Cost-effective one-piece design - eliminates the added expense and complexity of welded hangers, reducing material and labor costs on the job site
• Full-height joist flange - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, simplifying installation and reducing additional hardware
• Flexible nailing options (PAN minimum or maximum nailing) - allows the same hanger to address moderate or higher load conditions without switching to a different connector
• Compatible with engineered wood products and solid sawn lumber - provides reliable performance across a broader range of framing materials, reducing the need to stock multiple hanger types
• 12-gauge steel construction with G90 galvanized coating - delivers added corrosion resistance for long-term durability in demanding framing environments
• Available for sloped and/or skewed member applications - accommodates non-standard framing angles up to 45 deg., giving contractors flexibility on complex structural layouts

Why This Product

• One hanger, two load scenarios - the BA design supports both moderate and higher load conditions through minimum or maximum nailing, so structural requirements can be met without sourcing a separate connector for each condition
• Engineered to eliminate extra hardware - the full-height joist flange prevents joist rotation and removes the need for web stiffeners, cutting down on the number of components required for a compliant, stable connection
• Built for real-world framing flexibility - compatibility with both engineered lumber and solid sawn lumber, combined with options for sloped and skewed configurations up to 45 deg., makes this hanger practical across a wide range of residential and commercial framing applications
• Durable finish for long-term performance - the G90 zinc galvanized coating provides a higher level of corrosion resistance compared to standard coatings, helping protect the connection in moisture-prone or treated-lumber environments
