The Simpson BA3.56/24 Top-Flange Joist Hanger is built for engineered wood product (EWP) and solid sawn lumber framing connections where reliable load transfer and rotation resistance are priorities. Sized to fit a 3-1/2 in. x 24 in. member, this hanger supports medium loads with solid sawn lumber and higher loads with engineered wood products. The BA design accommodates both minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing for higher load demands, making it a versatile connector across a range of structural applications.

Key Features

• Cost-effective one-piece design - eliminates the added expense and complexity of welded hangers, simplifying procurement without sacrificing structural performance
• Full-height joist flange - captures the top chord of the joist to prevent rotation and remove the need for web stiffeners, saving installation time and reducing material costs
• Dual nailing configurations (PAN minimum and maximum) - allows the installer to match fastening to the actual load requirement, providing flexibility across moderate and higher load conditions in a single hanger model
• 12-gauge steel construction - delivers the structural rigidity needed for deep engineered lumber connections where thinner-gauge hangers would be undersized
• G90 zinc galvanized finish - provides enhanced corrosion resistance to help maintain long-term performance in demanding framing environments
• Available for sloped and/or skewed member configurations - accommodates non-standard framing geometry without requiring a completely different connector, keeping complex framing assemblies on track

Why This Product

• Engineered specifically for deep EWP members - at 24 in. tall, this hanger is purpose-sized for large engineered wood beams and joists where standard hangers cannot provide adequate bearing or rotation control, making it a direct fit for heavy-timber and open-web framing systems
• Rotation prevention built into the profile - the full-height joist flange locks the joist in place without additional hardware, reducing both labor and the risk of installation errors compared to assemblies requiring separate web stiffeners
• Load flexibility from a single connector - the ability to shift between minimum PAN nailing for moderate loads and maximum nailing for higher loads means one hanger model can serve multiple framing scenarios, simplifying inventory and ordering
• One-piece construction with G90 galvanized protection - combines structural efficiency with corrosion resistance in a single stamped component, offering a durable and cost-conscious alternative to fabricated or welded joist hangers
