The Simpson BA3.56/9.25 Top-Flange Joist Hanger is a versatile structural connector designed for both engineered wood products and solid sawn lumber framing connections, fitting an actual joist size of 3-1/2 in. x 9-1/4 in. Built from 12-gauge steel with a G90 zinc galvanized coating, this one-piece top-flange hanger supports medium loads with solid sawn lumber and higher loads when paired with engineered wood. The BA series accommodates flexible nailing approaches - minimum nailing with positive-angle nailing (PAN) for moderate load conditions, or maximum nailing to meet higher structural load requirements - making it a practical solution across a wide range of residential and light commercial framing applications.

Key Features

• Cost-effective one-piece design - eliminates the 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 removes the need for web stiffeners, simplifying installation and maintaining structural integrity.
• Dual nailing options (PAN and maximum nailing) - allows the installer to dial in the right load capacity for the application, from moderate to higher structural loads, without switching to a different connector.
• Compatible with engineered wood and solid sawn lumber - delivers medium load capacity for solid sawn lumber and elevated capacity for engineered wood products, giving framers flexibility across project types.
• 12-gauge steel construction - provides the structural strength needed for dependable joist-to-header connections in demanding framing conditions.
• G90 zinc galvanized finish - offers extra corrosion resistance, extending the service life of the connector in moisture-prone environments.
• Available modified for sloped and/or skewed members - accommodates non-standard framing angles, keeping projects on track when standard square connections are not feasible.

Why This Product

• One connector, two lumber types - the BA3.56/9.25 handles both engineered wood and solid sawn lumber at the same joist size, so framers do not need separate connectors for mixed-material projects.
• Rotation prevention built in - the full-height joist flange actively captures the top chord and eliminates the need for web stiffeners, reducing hardware count and speeding up installation.
• Load flexibility without product switching - by supporting both minimum PAN nailing for moderate loads and maximum nailing for higher loads, this hanger adapts to varying structural demands using a single SKU.
• Durable finish for long-term performance - the G90 galvanized coating delivers meaningful corrosion resistance, making this hanger a reliable choice in framing environments where moisture exposure is a concern.
