The Simpson BA4.28/16 BA Series Top-Flange Joist Hanger is a cost-effective connector built for double 2-1/4 in. x 16 in. engineered wood framing connections, with the added versatility to handle solid sawn lumber applications as well. Designed to carry medium loads with solid sawn lumber and higher loads with engineered wood products, this 12-gauge G90 galvanized hanger combines structural reliability with flexible nailing options - giving engineers and contractors a single connector that adapts to a wide range of load demands without requiring a different product.

Key Features

• Two-level embossment at the top flange - provides increased stiffness at the mounting point, improving load transfer and overall structural performance where it matters most.
• Full-height joist flange design - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, saving both time and material costs on the job site.
• Min./max. nailing options - minimum nailing targets moderate load demands, whereas maximum nailing allows higher loads, giving designers and installers built-in flexibility without switching connectors.
• Top-flange mounting style - simplifies installation by allowing the hanger to be set before the joist is dropped in, reducing labor time and improving accuracy on framing crews.
• 12-gauge steel construction - delivers the structural strength required for medium-to-high load engineered wood product framing connections in demanding applications.
• G90 zinc galvanized finish - provides extra corrosion resistance, extending the service life of the connector in moisture-prone or treated-lumber environments.
• Available to accommodate sloped and/or skewed members - adds adaptability for non-standard framing geometries, making this hanger suitable for complex roof and floor configurations.

Why This Product

• One hanger, two material types - the BA4.28/16 is engineered to work with both engineered wood products at higher load capacities and solid sawn lumber at medium loads, reducing the number of SKUs a contractor or builder needs to stock for mixed-framing projects.
• Rotation prevention built in - the full-height joist flange captures the top chord to prevent joist rotation and eliminates the need for web stiffeners, cutting extra steps and added hardware out of the installation process entirely.
• Load-scalable nailing pattern - because minimum and maximum nailing options are built into the same connector, the BA4.28/16 can be field-adjusted to meet varying structural demands without requiring an engineer to specify a different hanger size.
• Corrosion-resistant for long-term performance - the G90 galvanized coating provides extra corrosion resistance, making this joist hanger a reliable choice for floor and roof framing where moisture exposure or pressure-treated lumber contact is a factor.
